I played around with my setup for a bit trying to reproduce and have  
not been able to, yet. However, I'm running trunk and since I don't  
really follow the OpenGL stuff I don't know what may or may not have  
been improved from your version to mine.

Ahh.. see the misunderstanding of the work-around suggestion below...

Looks like it was just a misunderstanding of what was being suggested.

I guess you just misunderstood the original suggestion. It was to  
either re-encode the video (which I admit is a silly work-around and  
likely wouldn't even work) or "- turning up the overscan on playback."  
which is a valid work-around and only affects playback, not the  
original file.

It's been a long week. :)

Sorry I couldn't get to the bottom of it for you. I gave it a shot. I  
wonder if your GPU is powerful enough to use the OpenGL renderer to  
upscale to 1920x1080. I gets lots of weirdness when I try to play my  
1280x720 recordings on a 1920x1080 display so I keep mine at 720p now.
