I think that they should of been able to make the existing Vip series of dvrs work with hd to a 110 box via coax and give us either tv 1 or tv 2 in HD in two rooms. It shouldn't of been that much of a reach to achieve that. Instead a whole new series of receivers has to be invented .....AGAIN.
I think that part of Dish's problem the last few years was the TiVo lawsuit. They made changes in the VIP line (622/722) to try to work around the patent. Then it started to look like their workaround may have problems based on the TiVo trial so they did another entire workaround for the 922. Essentially they had too many of their resources tied up doing the TiVo workarounds and delaying their boxes and features. The XIP line was invented before they had the lawsuit settled, it probably had another workaround being developed for it.
