I ran across your Maine HDTV blog and was hoping you could help mewith an issue I'm having. I recently dropped my cable tv and I amusing an antenna. I am getting all the stations I expected with thetype of antenna I purchased (via information from antennaweb.org). Theonly issue I am having is the digital signal for wmtw channel 8. Withcertain hi-def programming the picture will skip (not pixellate). It'slike a very momentary freeze (less than a second), then the pictureskips frames to catch up. The audio is never disrupted. This happenscontinuously. The thing is that it doesn't happen with all hi-defprogramming. It only seems to be with filmed shows and movies. If it'sa talk show or sports program in hi-def, no skipping at all. In fact Iwas watching a talk show where the picture was perfect except whenthey showed a clip from the guest's upcoming movie. The clip did theskipping but when they went back to the interview, the transmissionwas fine. I just didn't know if this was a reception issue, set-upissue, or the station itself. Just wondering if you had any opinionsbefore I invested any more money into my setup. I currently have aTerk HDTVo antenna that is oriented in the proper direction (I amlocated in West Gardiner). I currently have it mounted in an attic.The antenna is an outdoor antenna but I was hoping to avoid the extracosts and expense of mounting it outside (weather, grounding, etc)unless absolutely necessary. Thanks for your time.
My response is as follows but please feel free to add your comments:
I have a TERK antenna as well so I know it well. I have converted to cable HD just recently but relied on my TERK and still swear by it. When I first started reading your email I thought "reception problem" regardless of what you might think or experience. It was my first impression. Then when you said it only skips when certain types of video are broadcasted, that one stumped me. To be hones after hearing everything, I'm leaning more toward your TV. I am assuming you have a wide screen HD TV with the built in tuner. Cinema film is shot in different frames per second than regular TV. So if that were the problem, I would ask that you check your TV setup for Cinema mode or something called Cinema 3:2 mode and play around with those settings to see if that's the problem. TV's also have different refresh rates (HZ). Like my older HDTV is a 60 HZ and my new one is a 120HZ and they are night and day different when it comes to screen refresh rates. I really don't think it's your antenna. If anything it's WMTW's signal or the Cinema (3:2) mode on your TV. Sorry I wish I had more. If it's any consolation, WMTW's signal is the least consistent in Maine.
Thanks for the quick response. I'll see if if any of those thingswork. I have 2 hdtvs and they both do the same thing on channel 8.Both are 720 resolution. One LCD, one plasma. I think they are both60HZ. I wouldn't mind you posting this on the blog just to see ifanyone else has the same problem with channel 8. Thanks again.
