I have had the 5067w DLp for about a month now. Whenever I go to HD channel, it will stop for a split second on picture frame, then jump ahead. It also is screwing up the sound at the same time. The cable guy came out and says the signal looks good to him. Has anyone else had this problem. It drives me crazy trying to watch football on it because it freezes for a split second. It plays just fine on DVD though. Note it does this with Cable card, and with just straight cable into the back. Does this sound like cable card problem or cable broadcast problem?
