I had a 921 for two years - never any serious problems, until recently, when the hard drive crashed. Dish sent me out a replacement 921, and this is exhibiting problems that I had never seen before.

Specifically, if I try to play back a recorded program while another is being recorded, the program frequently freezes. It will stop, then start up again. If I rewind, the "bad section" plays back correctly. The problem tends to disappear if I reboot the machine (but rebooting during a recording is not very attractive!). Then it will run fine for a while, before repeating the freeze-up behavior.

I contacted dish network the first time this happened, and simply reported the problem. Today, I talked to a tech CSR, who said the problem is probably related to multiple grounds in an HDMI cable. Huh? Would this affect playback only?

They are sending out a repairman on Friday, so I will learn some more. Still, this is not a problem that I have ever read about. I know that some users have had HDMI troubles with the 622. Has anyone had problems with the 921? If not, what is wrong?

Any help would be appreciated,

He is probably referring to a ground loop. This is due to multiple ground paths through your house wiring and your satellite dish ground. This is a very obscure problem and may or may not be causing the behavior. Have you tried unplugging the unit, waiting a few minutes and plugging it back in? This used to cure a multiple of ills on my old 921. And by the way the 921 has no HDMI output, it is DVI only.
