help! using pinoy's guide to rip dvd. d2v file is distorted

[tourist]

has anyone had this problem? my vob's look fine when I play them. but after I use dvd2avi to get my d2v file, there are horizontal lines that appear throughout the video. I could see them while scanning through the d2v file in tmpgenc. I then picked a small part of the d2v and encoded it with tmpgenc and the mpg I get from that has the same lines in it...
what is the problem? I have used pinoys guide and tools at a friends house that has a new system (AMD-1900) and his come out fine.

is it just that I don't have enough processor speed? I didn't think I would have any problems using a 500 MGhz PIII. anyway, any help would be appreciated.

thanks in advance...

The source is interlaced. That's it.

what do I have to do to correct this?

Nothing. Leave it as it is. SVCD support interlaced material. If you play the SVCD with a standalone dvd player and watch it on TV, everything will look fine. If you want to create a VCD, it is a different story. Then you have to deinterlace. You may play with different deinterlace filters for VirtualDub or Avisynth. There is no best filter and no best settings. It depends on the source and your personal taste. One prefer to blur the image, the other prefer a sharper image, but stick with some interlace artifacts. A deinterlaced MPEG will never look as good as an interlaced one. On the other hand interlaced material requires a higher bitrate than a progressive source. PC monitors are progressive. If you play an interlaced MPEG with a software dvd player, built-in deinterlace filter will do the job during playback. Usually it is a bob filter, that blurs the image quite a lot.
