Count me as one who could care less about a dual-HD-output DVR.
Have never (and will never) use my 622 in dual mode. When I get an HDTV for the bedroom, I will want another dual-tuner HD DVR dedicated just for that TV. I realize that there is some cost savings with using the 622 in dual mode to feed a 2nd TV. I want to be able to watch & record at the same time/have PIP/do whatever the hell I please when I'm watching TV. When used in single mode, the 622 is a tech marvel! Good GUI/Recording 3 tuners/watching off the HDD at the same time/etc.
