Strange issue with tmpgenc video in editing window...

[essentials]

I am having an issue with any version of tmpgenc that I am using.. When I go to the video editing screen to edit and cut portions of my video, the video is zoomed in, and only showing the bottom right fourth of the screen. It makes editing tedious and annoying.. It is still possible, but like I said tedious. I am having the same issue with real player and quicktime as well, in playback of each of their media. I tried updating to the latest versions, but it isn't really helping. I'm sure I have some obscure option checked somewhere that is causing this, but I haven't been successful in finding it yet... Anyone have any ideas?

I'm bumping this because I am still having this issue. It also does this on trailers I watch on the Internet... The video will be zoomed into the bottom right corner, and you can't see the other 3/4ths of the screen. After some searching on google, some people mentioned overlay issues... I remember a month or so ago I was wanting to take screenshots of something for a friend, and I think I may have changed my overlay settings in one form or another. I went into WMP 9 options, and set my advanced settings in the performance tab to default, thinking that would allieviate my issues, but I can still getting these issues. Furthermore, I don't see why changing my WMP settings would also affect quicktime and real video trailers, but I am having the same issue with those players as well. Any ideas?
