I encountered video problems after the recent software download. The video looked like the video problems one had years ago in the tube TV's when the horizontal sweep would lose sync and the image was squeezed into unrecognizable image. After a series of calls and a lot of frustration I dropped Directv for Comcast. Other issues with Comcast convinced me to return to DirecTv. I received new equipment and the problem returned. My old equipment; HR21-700 HD DVR using external hard drive Sony KDS-R70XBR2 TV Denon AVR 3808 CI Receiver New equipment; HR24-200 HD DVR Sony KDS-R70XBR2 TV Denon AVR 3808 CI Receiver After more phone conversations, decided to replace my HDMI cable. That did not fix the problem. I then reasoned that the problem must be software and it started with the original download to the old DVR. But the new one was not working either. So I researched the Denon receiver for software problems. That led me to connect the Denon to my router and download updated firmware. This download lasted about 75 minutes. The Denon turned itself on afterwards and the problem has not returned. It seems more of our devices these days are needing software updates.
