My 622 crashed two days ago. Dish sent out a tech as it could not be diagnosed on the phone. Dish waived all charges for the service call. The tech replaced the 622 with a 722. There is a distinct difference in PQ with the 722. It is nowhere as sharp as the 622. Everything else in the system is the same as it was with the 622. All cables, switches etc. Everything. I know PQ can be a very subjective thing, but after two years of using the 622, I know what I saw and the 722 is not close. I have checked all the settings on the MENU and they are all correct. I am receiving a 1080I picture at 16x9, just like before, but HD looks like a good SD picture and no better. Dish was very nice and very prompt and the tech was on time and knowledgeable. I hate to gripe, but should I?
