I'm curious why you say that. I have a 612 and haven't had much problem with it (some OTA reception early but the local station changed channels and all is better). I can record two satellite programs and one OTA. Granted, there's no 2nd tuner output, but since my 2nd TV is HD, that wouldn't really help me either.
So, what would I get if I go to the 622/722/722k? And I'm guessing there's a price difference?
The Issues I had with the 612, Was Hard drive bugs, Like dropouts on playback, and random delays between channel changes that lasted between 10-15 seconds. It reminded me too much of my Directv days using the HR series.:rant:
The 622 Had some HDMI issues , But I've had my since July 2007 and Never had one issue to date. I think the 622 is better then the 722k as far as glitches goes.
722k Bugs are
Random remote issues while using the IR remote number 1, Will not respond upon any commands, Unless you reboot. I think that has been since addressed with a software update, But I still use the TV 2 in RF Single mode anyway. So I don't care.
Also some random playback issues as well, Like a distorted playback picture while I'm recording something else at the same time.
This doesn't happed often, But I can recall 3 times in the last 8 months.
My 622 has never caused me any problems what so ever.
If I were you the 722k is the way to go , with the larger Hard Drive then the 612 and 622. Plus 2 rooms of service, make the dual rooms receivers a no brainer. The SD tv 2 PQ is still better then your basic cable, Granted its not HD ,but its by far Poor in quality.
