Did you use the 1280x720 wmv file or the 920x515 quicktime file?
The quicktime file was 1280X720. Unless your saying it had an original resolution of 920X515 and was stretched, but I don't see any indication of that. I did use the quicktime file and it looks awesome. It did give me some trouble when trying to convert it on my PC but when I used compressor on my Mac it worked just fine. Of course I had to come back to my PC to burn it to Blu Ray since apparently FCP/DVD Studio Pro doesn't think Blu Ray is very important and has no support for it. However, it looks awesome and is making the waiting much more difficult..
