I used to record TV with my ATI All-in-Wonder and then later I used a Plextor 402U external tuner/capture device. There would always be crappy quality and format lines or other extra information in the video. I guess HD recordings resolve the issue of crappy quality, though I imagine they're rather large files until converted to xvid or divx. Do the sub groups remove the extra format information with software as well? That's what always annoyed me about recording from TV.
