BleepingComputer.com: Wmv File Clean Up?

I would like to know, if anyone can recommend me a good WMV file clean-up program that strip the file from all crap that was get added into it.

The problem?

I tried to fix video play pauses with video from Panasonic TZ3 camera by updating the BSplayer to v 2.21 or so... It not fix the issue, but it added a trojan to my system. When I get rid of it, some WMV videos (rather perverted and rare, so to add) get busted - eg. it is not possible to play them anymore with old WinMedia player 7, or BSplayer Pro 1.41.
Media Player Classic and WinMedia player 9 can play them, tough.

I tried the ASF-AVI-RM-WMV Repair v1.82 ( http://www.repairvideo.com/ ) but it did not help me with this particular issue - but it did speed-up playing start of some RM files, so it does work somewhat...

Any ideas, suggestions?

If necessary I can upload on rapidsh*t some tame files, like:
Realtickling - Vibcharlotte3.wmv
...to be inspected 88 240 450 bytes, tough...

Anyone?
