Quicktime codec & XP

I upgraded to Quicktime pro and it doesn't recognize my AVI files (in movie properties it lists N/A though it's an Mpeg4 .AVI file from a Samsung camera.) and bounces me to the "Quciktime components" link.
The clips play fine on Windows media player, how do I get Quicktime to recognize/import the codec?

PC, Windows XP Pro

Nowhere have I found on your QuickTime link or within Help or Faq pages does it suggest that the version of Mpeg-4 that Microsoft decodes differs from the one QuickTime uses -instead, and proving my point, the promotional material says that:

"you can rest assured that the MPEG-4 media stream you create using one company’s product will run on another vendor’s player."

If that's not misleading I don't know what is. I feel duped having bought the QuickTime version for Windows thinking that I could edit and view "Mpeg-4" files. I would not have made the purchase if a caveat for Windows users was provided suggesting there were problems.
It is Apple's/QuickTime's responsibility to understand the issues affecting PC users when developing/selling a "PRO" version for Windows no?

Nope.
Your file is first in an .avi container. That should have triggered some Windows bell to go off. Even Microsoft (the inventor of AVI) hasn't used that format in ages.
Second is that the camera maker has chosen to create a file that falls outside of the MPEG-4 standards.
Your file is not MPEG-4 as far as QuickTime is concerned and you'll need to convert it before QuickTime can open it.
"you can rest assured that the MPEG-4 media stream you create using one company’s product will run on another vendor’s player."
Microsoft openly admits that their codecs do not follow the MPEG-4 standards.

This problems sounds similar to what I'm dealing with. I bought a G5 iMac and a Samsung digital camcorder (flash based) in order to make a short, promo movie. Now, I can't get the .avi files created to work in iMovie, QT, or the DivX player I tried. Of course, the files play fine on a PC.
Will the VLC player do something to allow me to use these files in my G5? Will it convert PC MPEG-4 over to QT MPEG-4? I'm just hoping I didn't waste a LOT of money on some equipment that I cannot even use. Please help!

Thanks, QuickTimeKirk!

Well, a few minutes ago, I tried to run a file through StreamClip but got the same results. However, noting what was said on the Squared5 link, I think I may need to do something with DivX. I recently installed DivX 6 for Mac in hopes of resolving the issue. It looks as though I now need to install the 3ivx codec to fix THAT. Does that sound accurate? This is my first Mac. So, I'm sure one could guess that it is also my first foray into complicated codec problems. I'll try the 3ivx and/or XviD codecs and see what happens.

hello ions and Kirk,
Kirk, FYI - one of the Windows links at Squared 5 above(specifically the "QuickTime Alt" link which I downloaded thinking it provided conversion software but instead suggests to uninstall QuickTime!) introduced something on my PC that prevents me from having QT on my desktop even though I chose not to install it. This has all been a bit of a nightmare since I'm on a deadline here.

The application that I've found most helpful at this point is not freeware but an AVI to Mp4 converter here at www.alloksoft.com, I haven't found freeware that will convert these files that reside on my pc as .avi but which according to Samsung use Mpeg-4 compression.

I've spent much of the last 3 days mucking through the VLC software suggestion above which ultimately didn't still save or convert the files to what QuickTime could read. Looks like I have to spend another $39(Cdn plus tax)unless someone can direct me to freeware that converts Mpeg-4 files that work fine on Window's (but appear to be identified as ancient ".avi" files!) to something QuickTime can work with.

PS: Kirk, did you know that .avi is still a standard file used up here for one of the worlds biggest film distribution companies? As a former IT trouble-shooter I find it troubling that rather than address the issue of some Windows .avi/Mpeg-4 files not functioning within QuickTime for WINDOWS one takes issue with either a) the user's choice of hardware, software or the makers of the operating system.

There should also be more info about QT's potential problems reading .avi/Mpeg-4 files provided for Windows users somewhere within the promotional literature for QuickTime Pro.

Man.
What a mess you must have right now.
I don't have all the answers and other users could have chimed in at any time.
My PC has "died" and I no longer am able to download and test PC versions to offer optional solutions.
That said, conversions are simple on each OS.
Open the file (install third party codecs as needed) and "Export". This should place your source file into a QT Player file and it could be used by the other iApps.
The .mp4 file extension is meaningless. M$ uses proprietary video codecs and they "hide" this in an .avi container. Since M$ uses non industry standard codecs, those exports will fail on "true" MPEG-4 devices.
The AVI "container" used by thousands is just a bucket that "holds" the info for video and audio reproduction. As long as the viewer has these de-compressor add ons they will never know (or learn) the difference.
MPEG-4 has some standards and QuickTime was used to develop them.
The .avi file was abandoned years ago by its creators.
The "Web" still serves up these out of date files formats only because it still works on older PC's.
If you want to display a true MPEG-4 in a Web page it must use the .mp4 (or m4v in some software like iTunes).
Or export using QuickTime using the MPEG4 Video codec and appropriate audio codecs that are supported by the device.
End of subject:
QuickTime does exactly what it instructed to do at export to other formats.
Making .AVI files that don't "conform" will not work.
