I looked at the faq's and this didn't answer my specific question... I just bought a premier that gives me 45 hours of HD or 405 of SD. My question is I am on digital cable from comcast and i set my recording quality to "Basic" because i figure the digital quality even on basic recording will be way better then before. However I do record programs from the HD channels in the lineup. So if i record from the HD channels is that taking up more space even though i am supposed to be recording in basic?
