Weirdest problem guys and it's driving me CRAZY!

I have a movie I recorded using SageTV in .mpeg format. I usually just boot up my DVD MovieFactory V. 4 with the latest patch and author a DVD just fine. Well recently, when I went to the Open Video File part of MovieFactory I can select some of the movies I pre-recorded, but if I move the cursor to some (specifically two movies), MovieFactory locks up completely and freezes. Eventually after pressing the "X" to close the window the program exits. This same movie can be loaded into Nero, Roxio and just about any other authoring program. It can also be played back without problems. So why would MovieFactory be kicking it to the curb? I've also run a scan disk on the drive, moved the file to another drive, used Video Redo to split it and try loading one or both of the parts and they lock up as well. I can move the cursor through the directory, but as soon as it hits on of those files it locks up. Crazy.

So my question is two-fold. First, anybody have any ideas what's going on? Second, is there an alternative authoring PLUS burning program to use. I'd use Nero or Roxio but both of those ENCODE before burning which takes FOREVER. TPMCGDVD authors but doesn't burn.

Thanks.
