Do you know if people with 4K tv's hooked up to regular HD boxes are having no problems at all with these out of sync episodes? The more I study this, I'm coming to the conclusion that 4K sets may be able to read and piece together the messy output from these cable boxes like it was a Dr. Seuss book. And as much as people with 1 year old 1080p tvs are going to hate it.. the best real world fix for the out of sync audio may be to retire it to the bedroom or let the kids use it for games and get the extra processing power of a 4k for the living room.
Yes, I am having issues with my X1 and my Samsung un65ks8500 and the a/v is out of sync. I have an Onkyo tx-nr515 for a/v control via HDMI. The video is a quarter second or so ahead of the audio, I have adjusted all the tv and receiver settings for audio sync, but there's no way to get them to sync up. I have even tried going to the TV hub directly and no luck. I put my Tivo back in play and there is no a/v sync. It's definately an X1 DVR issue.
Also on some channels, like CBS, it get real bad judder with the X1 box. Shows like Modern Family and Blackish are all herky jerky. On my Tivo, no issues.
