Hi, Harold.
Is it not true that HD stations insert the analog delay prior to the transmitter?
I wasn't aware that the receivers might be doing this as well.
In any case, drive-ins aren't transmitting HD, so there's no reason for a receiver to delay anything. I don't know any owner who feels having HD would bring enough benefit to the table to pony up for the Ibiquity licenses and exciters (per screen!).
Then, your server would have to feed audio to the system, several seconds ahead of the video, so the HD encoders have time to do their work. Someone correct me if I'm wrong, but I didn't think the servers could get that far ahead.
I'm really hoping this is just some fluke. We have a lot of HD stations in my area, though not many receivers. I haven't run into this problem at my place.

Another issue with the displays is that many of them can't be completely blanked. My Pathfinder will blank to gray, but you still have to cover it to eliminate the distraction.
For awhile, daytime running lights were the thing, and a couple of manufacturers decided the owners weren't smart enough to decide if they wanted them or not. For them, we'll hand out one of our rental radios. For the rest... we've built up quite a cheat sheet on how to shut lights off. It's rare that we can't get all the lights out, and I don't recall we've ever had more than one car out here at a time with the problem.
Otherwise, car radios aren't much of a problem at the drive-in. We've accepted our numbers aren't large enough to have much influence on anything, so we roll with what we get. We have more trouble with the higher-wattage sound systems they're putting in, while, at the same time, using the same (or smaller) batteries. We make good use of the 4 Costco jumper boxes we keep on-hand here!
