I didn't go through the code to see where it's happening, but either the StreamFormat is getting overwritten someplace or it's not getting picked up from music.xml. You can either fix the bug in the code or add
episode.StreamFormat = "wmv" before
screen.SetContent(episode) in appVideoScreen.brs if you're only ever going to play WMVs.
