Washington, DC NBC Sync Problem

1537 Views 14 Replies 7 Participants Last post by  DaveC56
Hey folks. I'm doing another roundup to see if DC area subscribers are still seeing sync issues on the NBC local HD channel. For me it's better than it was a couple of months ago, but still pretty annoying.

Also, the volume difference between the commercials and the programming is HUGE. Commercials are definitely quite a bit louder than the programming. I haven't noticed this on other stations.

Yes, both problems are still there on NBC4 DC....
Yep, still the same issue on NBC-HD in D.C. Actually, with all the local DC HD's I notice some lower volume issues, but much worse on NBC. Very annoying.:lol:
Does anyone out there know who the NBC engineer is for DC? It'd be nice to get a dialogue going with him to see if it is an NBC issue or a directv issue.

I see it. I am in Northern VA and there is a slight audio and display sync issue.
did not notice any problem...is this a unit-specific issue (HR20)?

I have HR10s...
I tried to watch My Name is Earl last night and this lag was unbearable. Is there anyone that I can call or email with complaints??
If it's possible for you folks, I'd suggest you go OTA with a CM 4221A and forget MPEG-4. I'm over here in Springfield(in a forest by the way) and I get clearer and sharper reception with the OTA signal. You can buy the atenna for 25-40 bucks. I didn't see the point of OTA until that big wind we had 3 or 4 weeks ago moved my LNB off a bit, didn't have locals for a week until the tech came out and re-aimed my dish. In the meantime I decided I needed backup and went OTA, glad I did, clearer, sharper and no Lip Sync! and oh by the way, the volume dropoff on NBC Channel 4 isn't near as bad with OTA signal as with MPEG-4. Just a thought

I am using a non-PVR HD receiver... H20-100.

What about for someone who lives in Western Loudoun County? What kind of set up would you suggest?

The CM 4221A should work. Was talking to a local installer and he mentioned that he uses the CM4221A in Loudon county, while it's further out then we are here in S-field, you are on quite a bit higher ground(generally speaking), and height is everything with these antennas. If the the CM 4221A is not quite up to par, then take the next step and go with the CM 4228. I CAN see a marked improvement in the signal quality of the D.C. locals(4,5,7,9, 20 and 50 you also get 4 PBS channels and the weather channels for 4,7, and 9) over MPEG-4 D*.

does anyone have any experience with using a indoor, or smaller outdoor, antenna, in the Burke/Springfield area? I saw a really small outdoor antenna at radio shack the other day, and wondered how well it would work...

( productId=2253765 , I can't post URLs yet)

It is very small and I could mount it easily...

I am assuming the bigger antennas are much more likely to have better signal reception, but would like to get away with as small of an antenna as I can without sacrificing PQ.
I was getting a very good signal here in Springfield for channels 4,5,7,9 and 20 and the subchannels with the indoor little plastic Zenith antenna plugged right into the back of the t.v.. The outdoor CM4221A allowed me to get the 4 PBS channels, WB50(or whatever it's called now) and a couple of music channels. The little zenith plastic model was 20 bucks on Amazon, you can have mine if you want to try it.
I'm far enough away that OTA wouldn't be feasible without a large outdoor antenna.

Anyhow, NBC sync SUCKS and the volume changes are ridiculous.

Who can we contact about this problem at DirecTV? I thought techs actually read these forums sometimes. This problem has been going on ever since I've had MPEG-4 locals back in September.
I'm located in Herndon, VA and yes, NBC (both OTA & HD local over the satellite) have lip sync problems. All other OTA channels (5-1, 7-1, 9-1, 20-1, 22-2, 26-1 & 50-1) do not have any sync problems at all.

Interestly, my old HR10-250 does not have any lip sync problems on 4-1. My UHF ATSC signals are fed into both HR20-700 & HR10-250 units.

Earl: Is DirecTV aware of this issue and how do we go about getting this problem documented?

Thanks,
Dave C.
