It'd be nice to have a summary of the bugs on one page. This thread is too large to read. The one's I've experienced in the past two weeks of having the 622 are the following.....
1) Harddrive failure message during installation (bypass and ignored by install tech)
2) pause bug (jumps to live tv while pausing a "live" event). Workaround is the pressing the skip back 10 and then play.
3) lost audio during item 2 as well. Recovered by changing channels.
4) audio dropouts on digital connections (mainly HD programs - OTA, 94xx channels). Occurs when using digital toslink connector only. RCA seem to work.
5) screen goes to black occasionally when pausing an HD recorded show - doesn't show paused frame. The status bar at the bottom is still present.
My 942 has the restart DVR event when it hits a corrupt portion of a program. I haven't seen this on my 622 (yet).
I have every one of these issues with my 622!
