Thanks for your replies so far.

So theoretically the hqdn3d option can actually make the avi look better than the DVD source? Are the default parameters OK when using this option?

I calculated the bitrate for Resident Evil, so it would fit on a dvd5. According to my calculations the bitrate should be 6000 but in the final encode the bitrate was something like 2400-2600. So I think it has no use to calculate the bitrate when one is aiming at a dvd sized avi. Unless I would encode something like LOTR.

PS: How do I make my reply indent beneeth the root post?
