I have just the strangest problem and don't know if it's the signal or my tv (Sanyo 52") Everyone once in awhile the sounds starts 'skipping'. Sometimes it will stop on it's own and go back to normal sound but just quicker to go down and back up a channel. It sounds like it's stuttering and very annoying. Has anyone ever had this problem or do you think it's the sound card in my tv? Thanks for any help.
