Tech visit a waste of time (trust me, several of us have tried), just recently the wfmj has been stuttering for a couple of days now for everyone, also 33 was bad when if first launched and has slowly been getting better (trust me, I feel for you). You will also notice that the audio does not match up with the picture at times on 21 and 33, I have found that the fix for this is to leave the channel on for a minute or two, then rewind live tv and then the audio and picture are matched up, no idea why this works, somehow the recorded stuff will line up while the live will not (might try this for the stuttering too)??????? This has been an issue overall for the youngstown area (that's why I dont think a tech will help--I'm in howland) Another solution might be to get the signals over the air, I do this with Fox 8 out of Cleveland, and watch the hd that way (I have a HR-21 so I had to purchase the AM-21 and it works perfectly, puts all OTA info into your guide, etc) Hope some of this helps...
