Greetings all, I've been a long time Tivo user, but I'm suddenly experiencing a strange problem on playback - either during live record or planned record. The problem I'm seeing is that if I touch the quick-back button, the video backs up, but the audio doesn't, and starts to repeat the section over and over like a broken record. When it stops that, the audio and video are no longer in sync. I can hit the pause button, the video will pause but the audio will continue until it "catches up." Here is a youtube video of what I'm seeing: http://youtu.be/WP_D2CHtyd8 What I've tried: imaging the current hard drive to a new hard drive, thinking it was a bad hard drive moved HDMI ports reset the TV to factory defaults (it's a Vizio) reset the Tivo with the new hard drive to defaults (erase everything) different Tivo remote that is known to work What I will try but haven't: different HDMI port try composite cable try component cable Any assistance would be appreciated. Thanks so much all!!
