I haven't bitched about it here because I know it would do no good. But from about 1 hour after I got the 621 software the following began happening to my receiver:
1) Occasional "flashes to black" that last lest than a second. the audio never stops though. These are random and happen on all three birds.
2) occasionally when you change the channel, the picture and sound black out for a second the way they're supposed to, then the same channel reappears for 3 to 20 seconds. During this time the receiver will not accept any other commands (not even from the front panel). Then the picture and sound black out again then I get a "Cannot find channel xyz on transp xx on xxx satellite" message for several seconds and THEN it changes channels normally.
4) occasionally when changing channels, the picture and sound go out normally then it returns to the same channel for just a flash. Then the new channel appears with the audio WAY out of sync. (about 10 seconds video to audio delay). If you let it go, it will correct itself over about a 5 minute span. If you change the channel up and back down it will be okay.
5) occasionally when changing channels, the receiver tells me it cannot see the satellite and it's "acquiring signal".
6) occasionally when tuning to a channel it will remain with a black screen and no sound for up to 20 seconds before a picture will come up. During this time it is possible to change the channel up to another channel aquifer that picture and sound and change channels back to the one that was staying black and it would pop up normally
7) occasionally when tuning to an audio channel, audio channels sound as if being played off of a vinyl album on a McDonald/BSR turntable with a worn out "blue" Sure stylus and worn out cartridge. Changing the channel up and back down will clear it up.
8) occasionally when turning off the receiver, it does not want to turn off. It will turn itself back on instantly. It's like a stuck key on the remote. But it happens on the front panel. After a few minutes, it will turn off normally.
9) The TV/Video toggle no longer works. You cannot get the receiver to allow any pass though RF signal. Luckily for me, I don't use this feature. I discovered this when I couldn't figure out why there was so much RF interference on the feed from the receiver in the family room to my bedroom. I pressed the TV/Video button quite by accident and SHAZAM! perfect picture. Pressed it again and a slightly fuzzier picture, but quite watchable.
I know I'm forgetting a load of "occasionallies" here, but you get the picture. When I first got the receiver it was perfect (two and 2/3 years ago). Two software revisions later (618) it started to act up. 619 was horrendous. 620 fixed absolutely everything. It worked great. Then came 621. I'm hoping 622 will get some of these "occasionallies" fixed.
Why haven't I screamed and moaned a bitch about it? Because all these thing happen occasionally and not enough to get me to take the time off my life it would require to get Dish to get me a new receiver that will end up with the same symptoms after the next software upgrade. :-)
