Worse how? There's some real unblended and interlaced sections in there. If you want to unblend it I think I'd do it to 29.97fps:
QTGMC()
Srestore(Frate=29.97)
If you use the default SRestore setting you get 25fps and jerky playback during the interlaced parts (like that scene in the dining room). And I'd leave off that CPU=6 thing. It's a tough call, though. Big jerkiness during the interlaced 29.97fps parts when doing it for 25fps, or slighter jerkiness, but much more of it, when doing it for 29.97fps. I don't think I've ever seen a source quite like this one.
