I was rescaning for new channels on the TV it scanned all of the channels on analog and digital and then went to save where it locked up. I let it go for over a half hour. I finnally had to power cycle it. Now it only shows the standard channels no DTV. If I rescan it hangs when it gets to DTV and never finishes. Ive used all the resets I can find in the menus and I have power cycled multiple times.
