I was watching this forum for about a month before deciding to install Dish Network in my home. I was worried about the audio problems concerning the 522's and at that time this would have been the DVR I was going to receive with the system. When the purchase was made the 625 was out and the 522 was gone. The picture quality is great but the sound problems seem to be common to the 625. I was watching a recorded show and there were 11 audio dropouts during that 1 hour show., not only that but it also makes some kind of chirp sound during playback.The first time I called Dish they had me re-boot the DVR and then unplug it for 30 seconds and she told me this would resolve the problem and that they were aware of this problem they were having., unfortunately it did not. So I called back a second time.I was told by this guy that they were aware of the problem and really had no fix for it. He said the best thing to do is that everyone who has this problem should call and they will fill out what is called an "uncommon" report, funny hah? should be called a common report. So anyway it seems that if enough people call,the status of the situation gets bumped up to the point where tech's who work on the software updates "get the message" that there is a problem and it is with allot of people and not just a few, according to him, this is the only way the issue's get resolved. He sounded sincere but to me it is bull****. Why would you come out with a new product and make it the same product but call it something else by giving it a new number? To me it is basically the same machine with the same software, having the same problems. I will call everyday if I have to and complain about the same problem until it is resolved or they can have there equipment back. I had 2 Tivo series 2 boxes with Cable, and although there were audio dropouts, it was not half as bad as this DVR. IMO, do the job, if you can't do it, step aside. Remember,there is strength in numbers., Or am I kicking a dead horse here?
