Okay, so, I've had a perfect success rate converting avi to mp4 using the MP4 Video Converter I bought, but it seems that any DVDs I rip to MP4 (with a ripping program by the same company) will import into iTunes, but then won't show up on Apple TV. I'm set up to stream, not to sync, so I tried syncing instead. iTunes completely ignores the two movies I ripped and copies the others, claiming it's doing 13 out of 13 files, when in fact there are 15. I'm not sure what's wrong. I'm converting into the exact same file type I use when I go from avi to MP4. I even tried ripping to avi first, then converting to MP4. Still, the files import and play in iTunes, but don't appear on the Apple TV. Any suggestions??
