new video format?

[barb123]

On syncing my i (touch) pod, the new video vocab lesson #19 doesn't get copied because it says the video format is not supported. On further investigation, it is a M4V format. I havent had any problems with the videos before this, is it a new format and what to do???? Thanks

I have the same problem with my SonyWalkman. Even if he is actually able to play mpeg4, the videovabs don't run and I have to convert them again in a mpeg4-file . After that everything is alright. I don't know why...
