lose dtv signal.
I have a new samsung p2270. when I press channel 8 on the remote the tv tunes to ATV. after much experimenting i found that if i press 1 and then wait a few seconds and press 1 again it returns to dtv. This may work on other numbers but 8 is definitely the culprit for tuning to atv. There is no atv/dtv button. Hope this helps.
