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!")
