I am having this problem with my previously flawless 622. It started with the 3.65 software upgrade and has continued through the latest fixed release. Every so ofter in a DVR'd HD show the picture just scrambles for a few seconds and then it goes back to normal. It looks kind of like it does during a storm. I had hoped the fixed software release would have cured it but it did not. I have also hoped it would just go away, but it has not. I really do not want to start playing CSR roulette in hopes of a remedy so I thought I would start here instead. Any suggestions?
