I would guess it was a local "thing" for you as I was able to record the first hour of Heroes tonight in MPEG-4.southtexan said:Tonight I tried to record Heroes in mpeg4 and my HR20 wouldn't. It would record it from OTA which I believe is mpeg2. But in mpeg4, all i got was a gray screen. I tried recording other programs (not Heroes) in mpeg4 from NBC with no problem. Anyone else have this problem?
