My HR20-700 has been having an issue displaying any video properly. It can be best described as if it's having a seizure trying to feed the image to the television. Audio is uninterrupted and matches the correct frame just right, no matter how much the video jumps around. I've rebooted, system tested, switched inputs, all with no luck. It's been running on the 0x62c update since 12/4 and I know it's not an alignment issue because all the signal strength returns are upper 90's and most are at 100. Also to further rule out an alignment issue is that my other receiver hasn't been affected at all. It seems to be perturbed more so if I rewind live tv and are behind in a program. Say I'm watching an half hour program and I'm 10 minutes behind. When the live program ends at the bottom of the hour to switch to the next program I am still 10 minutes behind only 20 minutes into the program, but the receiver will black my screen and jump to the bottom of the hour on it's own to revert back to live tv for the next program. Kind of weird. Any ideas? Thanks.
