I've had this problem for several months as well. I can download music. Can download tv shows. But movies create a constant "error 50" on my brand new imac. Figured it might be my brand new Cisco router so I hooked in directly to the Motorola Surf Modem (6580). Same problem. Tried to go wireless. Same problem. Took a trip last week to the Florida panhandle and used my laptop wirelessly to connect to Itunes. No problem!!!! Fast downloads, none incomplete. So I figured it was some weird quirk with my Imac so I tried the laptop at home to download movies. Problem!!! Same issue as with the Imac. The only difference between the two locations is a different cable provider....It doesn't appear to be 11.0.2 since that's what I have on my laptop and it worked fine on whatever cable and router they had at the rental house... Very strange, very frustrating (as everyone else has expressed) and unable to really isolate the problem. Figure it's not my router because I used both the Motorola Surfboard (direct connection) and the Cisco (direct connection AND tried hooking up wirelessly). Also tried the other solutions recommended (clearing the cache, restarting, etc.). No luck...What's particularly weird is that the problem is about 2 to 3 months old and I can't remember what changed 2 to 3 months ago (i.e., upgraded to 11.0.2?)...
I forgot to add one detail which might suggest a point of reference. When I "check for available downloads, I have to log in twice to my account. When I was in the Florida panhandle, I only had to log in once....BTW, I have Brighthouse Lightning so speed shouldn't be an issue causing it to time out. I've experienced what others have where a movie will half way through or more and than restart...Still waiting after 2 weeks for the Hobbit (not HD version) and Zero Dark Thirty (not the HD version) and Les Miserables (not the HD version)...As another aside, I purchased a few of the Blue Ray movies that come with an "ultraviolet digital download" and you log in to Itunes, punch in a code and it downloads flawlessly (Les Miserable and Zero Dark Thirty which I purchased as DVDS just to see if I'd have the same problem with other downloads which I don't)....

Actually, this may very well be the source of your issue.
I have wrestled with the -50 error a lot and I too have Brighthouse Lightning. Some time last year I read that the 'acceleration' process Brighthouse (and some others) use to get their higher connection speeds actually causes the problem. I am afraid I cannot cite the source article as, despite searching for it, I never managed to locate it again. But like you, I can download without issue at other locations, but my home location is very problematic. Downloading at low traffic times seems to help.
I don't believe it is a time out issue, it seems to be a file corruption and/or buffering problem.
Of course, Brighthouse denies it is their issue...

You may be right; the common thread(s) seem to be Brighthouse and 11.0.2-seemed to work before so I tend to believe that it's some kind of perfect storm combination with these two items. I don't seem to get the problem with tv shows (one at a time, not a series) and it seems to go okay with documentaries that are under 1 gb. It may be some "governor" that kicks in when the download is more than 1 gb or so. I tend to download at 2am-4am EST so I wouldn't think that it would be heavy traffic but who knows...Hope it gets corrected because, like everyone else, I like the "quick availability" of Itunes and don't really like to go to the store and have to purchase the blue ray combinations that come with an ultraviolet digital download....
I was having this same issue (Error -50 and 8008) with the download either stopping, or falling back a few hundred MB and restarting - and never ending. The problem had been going on for a couple of weeks. I had tried the various suggestions of deleting the iTunes download folder, clearing iTunes' cache in preferences, signing out and back in with my Apple ID, etc. I had contacted iTunes support too and didn't get anywhere with their canned suggestions. However, they did suggest I try digging through the Apple Support Communities, and so here I am. I'm posting this to confirm my solution.
As background, I'm on Brighthouse's network in Central Florida. I recently moved up to their 30Mb/s service, at which time they pulled out the old cable modem I used to have (that didn't cause these errors) and replaced it with a newer unit (Motorola SBG6580). Looking at stephenfromdelaware's posting earlier in this thread, I realized the problem was that the new cable modem was actually more than just a modem - it had a router in it too. The fact that I had my own trusty wireless router plugged into what I thought was just a cable modem was actually causing the data to flow through two routers between my computer and the web. In essence, two firewalls, two DHCP servers, etc etc. Not good.
Once I realized this, I knew I had to turn the SBG6580's routing off and turn it into bridged mode. I was unable to get into the settings (http://192.168.0.1 default) because Brighthouse is apparently using their own custom password and it was not disclosed to me. A quick call to Brighthouse fixed this though. I called in and the person who answered understood exactly what I meant when I asked for help turning the cable modem to bridged mode. They transferred me to higher level support immediately, and the tech reprogrammed the cable modem remotely within a couple of minutes.
After this, I signed back into iTunes and was able to download the large movie files that had been giving me problems for weeks right on the first try.
I'm happy it's fixed, and I have to thank stephenfromdelaware for his earlier post. That being said, I'm still disappointed that this problem appears to be exclusive to iTunes and the way Apple's software manages downloads of large files, and appears to be hyper sensitive to latency, time outs, etc. I do not know whether it's a client side issue or a server side issue for Apple, but the fact that I never had any problems downloading similarly large files from other sites tells me Apple could do better.
Good luck everyone. Hopefully someone will find this useful.

Absolutely brilliant!!! Thanks much. Have been trying for several months to "crack the code" on why I couldn't download movies and why I couldn't update Itouches and Iphones. I called Brighthouse and did exactly what you said and it worked!!! Hope this helps everyone else and very much appreciate that you took the time to walk through the issue and the steps you took to get it right.
I have been struggeling with the -50 error code problem and finally worked out what was causing the issue which doesnt appear to have been covered here.
I am storing my itunes media via NAS HD shared over the network using my Wifi Extreme. This is formatted using FAT32 due to a Windows PC also sharing the data.
Everytime my purchased movie downloads would fail at exactly 4gb and display err-code -50. The usual method of deleting the download in the iTunes download queue and logging in to my iTunes account to reinitalise the download would also fail leaving me purplexed, until the penny dropped.
If you are sharing your iTunes drive via a NAS formatted in FAT32, this file type only supports files SMALLER than 4GB.
Which makes large file sized movies, such as Avengers Assemble (as in my case) be impossible to download.
The only solution is to move your iTunes media to an OSX extended file format.
The following alerts may appear when trying to download purchased content from the iTunes Store:
"There was an error downloading your purchased music. An unknown error occurred (-50)."
This can happen when the connection timeout occurs while downloading purchased content from the iTunes Store. Certain types of software may also affect the way a computer sends and receives information from the internet. Here are a few examples of these types of software:
- Web Accelerators
- Ad Filters
- Virus Protection Software
iTunes, Windows Vista, Mac OS X 10.4, Mac OS X 10.6, iTunes Store, Windows 7, Mac OS X 10.5, Windows XP
If you have any of the software listed above, and you cannot access the iTunes Store or complete your download, you will need to configure these applications to allow iTunes to connect to the Internet.Refer to the documentation that came with that software, and if necessary contact the software's manufacturer. You will need to configure the software to allow the following domains to send and receive data from the Internet.
If a web accelerator appears to be causing the issue, contact your Internet Service Provider (ISP) or the software manufacturer. If your computer is on a network, you may also want to try using a different computer on the network, or discuss the issue with the network administrator.If you find that this error only occurs while attempting to download video content, you may be able to resolve this issue by deleting the cached video files of the download, then resuming your download."Error (-50)" when downloading purchased videosDeleting the cached video files of the download, and starting the download again from the beginning, often will resolve this issue.To find the cached video downloads:
- Navigate to the downloads folder on your computer. This folder can be found in the locations listed below. Note: the "iTunes Media" folder may appear as "iTunes Music".
~/Music/iTunes/iTunes Media/DownloadsNote: The tilde (~) refers to your Home directory.Windows Vista:
- Locate the folder that contains the cached video file for this purchase.
In Windows Vista and Windows 7, the folder will be named for the purchased video, and the name will end with .tmp.
Example: The Dundies.tmp
In Windows XP and Windows 2000, the folder will be named for the purchased video, and the name will end with .m4v.tmp.
Example: The Dundies.m4v.tmp
- Move the .tmp folder for the affected purchased video to the Trash or Recycle Bin.
- Open iTunes.
- Choose Store > Check for Available Downloads.
- Enter your account name and password and click the Check button.

This problem has been going on for a long time, I've tried everything that been suggested by Apple and its users and I still end up with problems. I've messed around it with so much that I started getting other problems with movies that I haven't downloaded. I finally gave up and rented from Microsoft Video and it worked with no problems. Obviously the problem lies with Apple, it shouldn't have to do a bunch of trouble shooting just to watch a movie.
