Seems like a few of the HD channels have this problem. It's a black screen for about a third of a second, every 30-45 seconds or so. VERY annoying. Tried to call MTS tonight, but got the message they are so busy that I should call back later!
not sure what you are seeing, I don't see anything like that on my HD channels.
Try watching about 5 minutes on NBCHD, and let us know if it happens. It's a very brief "flicker" of black, and sometimes the audio "skips" as well. Usually happens every 30-90 seconds, even during commercials. I noticed it during Law and Order SVU last night. It shows up in recorded video as well.
has anyone called in to let MTS know? I don't see this so it may not be the same for everyone. I wouldn't wait hoping MTS reads it hear and fixes it, best is to call and give them the details like time and date and channel of the problem so they can track it down.
