nbc

Only on NBC is there of synchronization problem between audio and video. I google searched this a week ago and found out that it's a network problem. I would think by now enough people have complained and The NBC Network and its affiliates have to be aware of it. If I'm not mistaken I would think  there's been numerous complaints. I'm sure it's not a complicated fix. So why the f___ isn't anything being done about it? It's even that way when it's not network programming. Ch 4 in Detroit. You try to watch the news on Channel 4 here and it's like you're watching some kind of foreign lip sync movie. It's very very irritating. Not so on any other network. Any thoughts?
