Okay, now that I've gotten the mp3s working, maybe someone could help me figure out why I can't view mp4s? I've copied and pasted them from my computer into the "videos" folder. When I open MyStuff/Videos in the phone, the files are there. However, all I see is a music note icon and when I press the play button, I only get audio. If I go to Entertainment/Video Player, the videos are not there at all. If I open the Walkman and select "all artists" I can play the files, but they're audio only, still no video.
I also tried copying the files into the VideoDJ folder instead, but of course that didn't work either.
These are just MP4s that I downloaded from YouTube. Nothing longer than 7 or 8 minutes.
