So I got this PSB dance performance video recorded in my Windows Media Center DVR, and now it's time to edit it.  Unfortunately, 
DVR Edit does not work, giving a merely 1 minute length when loading the video into the application.  Then I try this 
DVR-w-WMV.  Well the application doesn't even start in Windows 7.
So I am trying Windows Live Movie Maker.  It recognized the file, and I did all the editing in it.  Strange thing comes when I tries to save the result as 1080p video.  It simply stay at 0% complete like forever and ever.
However, when I tried the second best quality, which is High Definition 720p, it worked, excepted that the aspect ratio was not right.  So I select [View] [Aspect Ratio] and chose Wide Screen.  Finally everything looked right.  The 16 minutes 16 seconds video took 17 minutes to compress, and the file size is 705Mb.  Not too bad.
