I have a 30 gig 5 generation iPod Video. This specs page: http://support.apple.com/specs/ipod/iPod_with_video_30_60_GB.html lists that this ipod can playback video at a max of 320 x 240 for H.264 and 480 x 480 for mpeg 4 video. However, I'm able to play downloaded TV shows such as Lost, which are 640x360, but I can't play movies that I've converted using videora that are at the same resolution. If anyone could explain to me why this is or has any thoughts about this I'd appreciate your input.
