A bit of history on the HDTV beginnings-
I was one of the pioneers that had the Dish 5000 with the 8VSB modulator connected to the Panasonic Tuner with the original DVHS VCR and recorded HDTV off of Dish's HBO channel when it went HD. That was before the days of compression below 19.4 mbs and the quality I have on those early DVHS tapes is stunning. I still have nearly 400 HDTV movies and other programming recorded back then. But, today, I play the tapes on a JVC DVHS VCR because the Panasonic / Dish 5000 system no longer works.
One individual, who pioneered the recording of HDTV by developing a link between the DVHS recorders and the satellite receiver sources using 1394 connectivity was Richard Adams. He is to be credited with bridging the gap that was left with the demise of the 8VSB technology of the Dish 5000 and satellite receivers that did not have 1394 output. He developed a retrofit kit to add 1394 firewire to various sat receivers both D* and E* I am proud to have been a part of his development work on this as a beta tester for both D* and E* sat receivers.
Back then it was still questionable whether HDTV would ever become a major player in the Digital TV formats. Also was the MPAA scare where MPAA wanted to kill HDTV and was openly afraid it would kill their industry of movie production. Yes, today, we laugh at this but back then only the vocal pioneers and a few strong manufacturers like Sony and Panasonic worked hard to make it all happen. Of course, Panasonic's work in DVHS was muscled off the market by the MPAA, but JVC picked up the call and kept consumer HDTV recording alive strong enough for the people at Echostar and a few other smaller operations to develop the 921 DVR. This DVR was the pioneer in HDTV, not the TIVO as many would like to believe. The HR 10-250 arrived about 7 months behind the Dish 921 and while #2 it was a better more robust technology for its day. I believe the HR 10-250 HD TIVO held the title of best HD DVR until Echostar introduced the VIP 622 series. I feel the VIP 622 and its successors givers us the final HDTV recording maturity, the happy medium between the MPAA paranoia and us, the consumer who just want to have the ability to watch and enjoy the programming that can be in HDTV.
