Random red, blue and green dots. Converter, codec or comput

[trett]

I've been attempting to encode video files with both TMPGEnc and Virtualdub and I keep getting random blocks of red blue and green showing up in the black areas of the video. Does anybody know what causes this and how I can fix it?

more info please.
what is your source?
when do you see these blocks? preview? during encoding? on your computer? in your DVD player?

etc.

I'm mainly encoding from two sources. I have either high quality DivX files that I want to encode to MPEG-1 files to put on a VCD or large MPEG-1 files (~6Mb/s) that I captured with my ATI TV Wonder card that I'd like to reduce to put on a VCD. When I attempt to conver either one in TMPGEnc or Virtualdub, I notice the dots in the preview pane during encoding, and sure enough, when I play the newly encoded file later, they're all through the picture. I haven't tried making a VCD of the files, but I have a sneaking suspicion that they'd show up there, too.
