Mp4 movies (which played on iPhone 3g) not playing on iPhone 3gs

I had converted a lot of avi. Files into mpeg 4 format and was able to play them on the iPhone 3g without any problems. I bought an iPhone 3gs 2 days ago and have transferred my video files (through iTunes) onto the 3gs. I have found that some files will play, but the majority now have a green background and are very pixelated as it moves from one frame to the next. The audio appears to be ok. Has anyone else come across this problem? It's very frustrating! I would not have got the 3gs if I knew I'd have this problem.

Pc, Windows Vista, 64-bit

In iTunes, select one of the bad videos, then (in the Advanced menu) "Create iPod or iPhone version". After you have done that, sync the new versions to the iPhone.

The new 3.0 seems less flexible in what it plays.

Thanks for you reply, but... I've tried this and it says that the file is already using the correct format.

I spoke to the Apple Store a little while ago and the chap told me that the Iphone 3gs shouldn't be doing this and it is most likely a hardware fault. He said to try a 'restore' thorugh itunes and if this doesn't rectify the problem take it to the Apple Store (Regent's Street). If they can't fix it, they will replace it.

I have a similar problem, iTunes tells me that none of my movies have been rented. They used to work and now don't


Maybe you need to log in again ... In iTunes, log in to the account that rented the movies. Then sync the iPhone. That should set the iPhone on that same account.

I'm having the same issue with my 3GS, mp4 files converted with Aimersoft that play on my wifes 3g running OS 3.0 (which use to be mine and played everything ok) but my 3gs gives me the green screen. Audio is OK however, I spoke with an Apple expert and they don't have an answer. My carrier is suppose to send me a replacement but of course they are out of stock. Hopefully it's just a software bug since it was **** getting this 3GS!!

Anyone find a fix yet?

I have a solution, at least it worked for me. I looked at the video file that I purchased from iTunes and a video I converted my self and found that the videos that were working were running codec H.264. So I went back to my old videos that were working previously and converted them using the above codec and all the green twitching mess was gone. I used Wondershare to convert my DVDs to the format. I guess the 3GS does not like the old codecs. All the videos are working perfectly now.
