Hey all, I love my new iPhone, and it worked almost perfectly for what I need out of the box (and after the sync with my G4 of course)! However, I do have this one nagging problem. A lot of the MP3s in my music library won't play on the iPhone's "iPod" mode. It will show the play time counting down, but after about 5 or 6 seconds of silence it will just jump to the next song. I have noticed that this never happens on CDs that I ripped myself, or on songs I've obtained recently. It mostly happens on files that are a few years old and of... let's say "undocumented"... origin. I don't have any problems with these files on iTunes for OSX. The encoding I have used to get MP3s I have ripped (and are confirmed to play on my iPhone) was done by SoundJam, iTunes and LAME. I have never owned an iPod, so is this a known issue that some kinds of encoding won't work on Apple devices? Also, is there a way I can have iTunes scan my entire library, and give my "undocumented files" some sort of amnesty by re-encoding them? Your thoughts would be appreciated.
