When you say you lose footage, you mean like edges of the video, right? Not like actual seconds or minutes of the video being chopped right? If that is the case, I might hazard a guess that overscan is your problem. The short story: TVs will crop off a little bit of the side of video in case the edges are not smooth. Computers don't do that, hence you can see all the edges on the WMV file. If I understand you correctly, that could possibly be the problem. The bad news is I don't know of a program to fix this. However, I think I read somewhere that you can mess with your TV and get rid of overscan, but at the risk of maybe ruining something. So sorry, I couldn't really help.
