Can't export any video from MT

[mvv0105]

I have a very strange problem - i tried several times to render video with different codecs, and that's a results:

- WebM: just don't work at all, immediately going into main menu, don't know why.
- Default codecs: black screen when rendering + video file is broken.
- Ffdshow: first time i get a corrupted 5 first seconds of video with 1 gb size (other part are separate and perfect), other times MP gets crashed with "Runtime error" every time i trying to export video...
- Lagarith Codec: gives a very-very lagged video, or my GPU is too old for that (Nvidia 9800GT).
- h264vfc or something: i tried to render video with bat-file tonight, process are started, on next day i find my PC is off, and no video at all, only left part of video is made even before i go to sleep. WAT
- Don't use compression: TOO MANY space are required, i have only 100 gb, and nothing more...

My first thought: Some files are corrupt, so maybe try a reinstall of the game....?
I would try:
1. Install over top of existing files;
2. Uninstall - selecting 'save your game files, profile etc' button - then a clean install.

My second thought: Maybe video drivers need updating.
