I tried the video in Windows Media Player and it seemed to be ok. I'm going to try and update Media Player if there are any updates available and see if that helps. Another thing I noticed is that in streetdeck, if I open a .wmv file, the video will open in a separate window on top of streetdeck and streetdeck displays black with the video controls only. if i restart streetdeck, it goes back to normal. that seems to be only with .wmv's though.
