I have been having problems with some wmv and mp4 videos (both formats the desire supports). Some files of these types play back fine, but a good amount of others play with a black screen! Anyone else have this issue? Some videos are HD others are not, this does not seem to be a factor. I have tried resizing some wmv's to see if that would make a difference, but it didn't. Whats the best / fastest etc open source / free / paid application that can convert different types of video into format / resolution that is compatible with the desire? I would be interested in something that I can queue up files and leave it running overnight etc I head 'handbrake' mentioned alot.. can this have wmv and mp4 as input? thanks in advance!
