As far as the DVR part goes, YES I've had the same problems. I have 3 510 DVR's, all that worked perfectly untill 11/1/06. Then, at random, 1,2,or all of them would not record off the guide. We replaced on 510 with a refurb, which lasted 8 hours before the hard drive failed, replaced that 510 with a 522. All this took place between 11/2 and 11/14. After numerous phone calls and a tech coming out to my house to tell me all the hardware is fine, I finally got a supervisior to admit that there is a software issue that they are working one. Now, as of 11/14, we have had no problems on any of the receivers. Maybe they fixed it?? Fred
