I have several movies I have ripped using handbrake in iTunes and have had no problems watching the movies on an AppleTV I used to have. However, now I want to transfer some movies to an iPod Touch and I get an error message saying its not in the right format. When I look at the file description, all the movies are in M-PEG 4 format with the H.264 video codec. The file extension on all of my movies shows .m4v which I thought was the problem so I changed the extension of one of them to .mp4 and that didn't work either. Any suggestions or helpful advice? Thanks.
