I'm trying to run a video in gbpvr and the video is being resized automatically. It's in the avi format. When I run it in VLC outside of gbpvr it runs in widescreen format with bars on top and bottom, clarity is great. When I run the video in gbpvr, it's resized to 4:3, the video isn't as clear, and overall just disappointing. What can I do to fix this?

Also, I can't rewind LiveTV, I can pause, go to the beginning of the recording, and then can't fast forward from there. Also the jump forward button does nothing either. The only way I get back is to change channels. What do I need to look at to fix this?
