Sound and picture are out of sync on HD channels. Makes HD difficiult to watch. Re booting tivo, or changing challes up and down doesnt help!
Welcome to the community and I'm sorry to learn this is happening with your HD channels.
Is this only happening on HD channels and if so are there any in particular? Also are you using any surround sound equipment?
Looking forward to hearing from you.
