Well, they really screwed up my 921 with this one. Banners show wrong OTA channels. When tuened to one, it shows something else. Fast forward is totally pixelated, freezes and then jumps to the end of the recording. This is just what I've found so far. If they think by screwing up the 921, I'll buy a 622, they have got another think coming. They need to revert to L276 and leave it alone. Mine has not been right since then.
