Kodemonkee, I would say the unit is defective. My new 9242 has no problem with HDMI feeding a 2006 Hitachi plasma, and no other problems so far. I use it it "dual" mode and the composite output on TV2 works great, as does the RF ch 60/62 which I feed back to my little TVs in bedroom and kitchen.
And thanks Archangel, Tom, and barter for answering my question re the HDD being always on. They could have a "wake-up" feature prior to a download or timer recording, or some sort of cache memory. I really see no need to keep an HDD running all the time. It's rather wasteful IMHO.
