i noticed when the raiders/ chargers game was over and my local CBS switched to bonus coverage of the pats/ cowboys game- the picture on the ST HD channel was much nicer than the picture on my local CBS HD channel (los angeles). i get my locals via directv not OTA. but there was a definite -fairly big- difference. this was the first time i had a chance to compare the same two games on different channels since whatever the local affiliate is showing is normally blacked out on ST. wonder why there was such a big difference?
