The problem is with the capture, not the playback. Are you capturing
over coax? If so, using svideo IN will help. You can also check your
capture rate settings in Utilities/Setup>Setup>TV Settings>Recording
Profiles. Bump up your bitrate to something insanely high and then
bring it down until you have a nice balance of "acceptable" quality
and "manageable" file sizes. What those settings are varies from
person to person. If you are transcoding, check the transcoder
settings there, too. Note that on the Quality sliders on the
transcode settings, lower numbers mean better quality. I've been
burned by that before. ("I keep raising the "Quality" and it still
looks like crap!")
