what's the best way to do this? personally i have only tried to do this with Womble Mpeg Wizard, i found that the filters aren't that great and the encoding time was severe. theoretically, it should work to use Vdub Mpeg2 to frameserve a regular mpeg encoder(CCE). i am not as familiar with AVISynth as i probably should be; i don't even know if it can frameserve mpeg2...??? specifically i would like to try to apply an "undot" type filter to an mpeg-2 that was originally recorded off of VCR. i would certainly appreciate any ideas for cleaning up mpegs.
