For some reason, I can only get one WMV file to play. Other WMV and avi files will play with only sound and no video. anyone know what is wrong?

I know this is said a lot on the forum but double check your conversion of video on the ipod. I found that if you take a source and use a convert program such as videoera it creates an mp4 file and seems to work fine with the system. I am running a 900bt and it works with the mp4 files as video. Only problem i ran into is that the unit doesnt always recognize the video and i have to press somewhere on the screen to get the ipod control back up, then hit play, then hit hide. I then wait a few seconds and it plays fine after that.
