Tonight I was recording Law & Order:CI off NBC KNTV (11.1) in HD in San Jose from 9pm to 10pm. I started watching the show at 9:35pm, time-delayed. The 921 immediately hung as I pressed the forward 30s key. The picture got stuck on the last frame before fast forward. A couple of minutes later, the 921 rebooted itself. Around 9:40pm, the 921 came back on. This meant I had lost 5mins of the show. I attempted to watch the show again from the beginning. And then the 921 hung again, and rebooted again !!! After that, I called Dish network . I got transferred from operator to support, to advanced support. There, I was told that there are problems with the DVR functions on local channels, and I shouldn't use them until they get fixed. Uh? I pointed out that DVR on local channels is the main reason I bought the 921. I asked when the problem would get fixed, but there was no estimate. I asked if I could get a receiver that worked, such as the 942, but I was told that wasn't possible and those receivers are only available for retail sale. So, I asked to get transferred once again to cancel my Dish network account. At first I was offered one month of free service for the inconvenience., and a replacement 921. But I explained that I paid $500 for the unit and I expected it to work, and the one month free service wasn't going to make up for that. As to the replacement 921, I have already had one which helped nothing, and the problems are clearly software rather than hardware related, so I declined . I was offered the option of getting a non-DVR HD receiver. I explained I already had a non-DVR OTA HD receiver and didn't need another one (I primarily watch OTA HD, not satellite HD). Next, I was told I could trade my 921 for a 942 with a local retailer. I don't know of any retailers that do exchanges, but if they did I'm pretty sure I would have to pay extra, which I'm not willing to. I already paid for the 921 and I want it to just work. I was told I could also just not use the 921 and use my other DVR-508 which works fine. That would be OK if I hadn't already shelled out the $500 for the 921, and they weren't willing to give me a refund on it. So, Dish network lost a customer of 7 years tonight. I'll be watching the remaining shows in my DVRs, assuming they don't cause hangs. And after that I'll be listing them for sale, assuming nobody at Dish figures out a way to get me a working receiver.
