Two of my Mpeg-4 video files won't play. All the rest play normally on quick time, itunes.

Also on the video files that won't play the cover art is gone and the artwork tab on itunes is now gray and I can't access it. Strange that it only happened to two files. One of the files is still on my ipad and it plays fine on there.

Additionally, when I click get info the video Dimensions for these two videos are 0x0 and the total bit rate is 0! What happened to my 2 video files? The size of the videos is still a couple Gigs and the bit rate is normal.

10.6.8
i tunes 10

Thanks!

It plays in VLC with no sound or video. I think the files are somehow gone, not sure how which is why i started the thread but they have no dimensions or total bit rate so something happened to them.

Yep, sounds like the files are damaged.

Analyse them with VideoSpec (I prefer that, though it hasn't been updated since 11/2009), MediaInfo Mac (10/2010) or MediaInfo (4/2011, there is a Mac OS X version to download, VideoSpec and MediaInfo Mac are using the same library as MediaInfo) and attach the reports to your next post.
