I have some workout videos in AVI format, and I wanted to get them into iTunes so I can stream them to my ATV3. I transcoded them with Handbrake to get them into iTunes, and I used the Apple TV 3 preset, and I DID NOT change any of the defaults. So when I move the file into iTunes and play it on my Mac directly from iTunes, all is good, audio and video are in sync. But when I play them on my ATV3, the audio and video is so out of sync that it's unwatchable. I have a HUGE movie collection in iTunes, and I've converted from AVI before, but never had this issue. It seems only these workout videos have a problem. So why would it be only these videos, when every other video/movie works fine? I'm not sure what version Handbrake is, but I know it's the latest version, I always update it when it asks to. Also, if I play the videos natively as an AVI without converting, the work fine, on my Mac and on 2 windows machines I have in the house. Thoughts?
