Thanks everyone for your answers. It has been very helpful. While I'm pretty good with most of the DVB stuff, the permissioning was a bit of a grey area. Even the manufacturer was unable to answer the question that you guys handled quickly.
BTW, for those who mentioned CRTech, thanks for the plug. I am one of the co-founders of the CRTech list. If you look at the archives or past messages, sort them by author and look for Michael. That would be me.
Regarding the comments about a lot of religious programming. That particular DVB feed on TP17/4043 has some 35 or so channels for the Christian Radio consortium or CRC. Hence the whole thing is Christian programming. Other than possibly the Moody channel you will not hear any station IDs as these are feed channels. Local radio stations take the programs and air them on their own schedule. Almost everything there is free to use. There are a few of the feeds which require registration with the provider to get your receiver authorized for it. Some channels, like Salem A, Salem B, and Salem C are subscription channels, which you actually have to pay for to use.
The thing that I was unable to find out was how the permissioning took place. For example, if you do not have a subscription for Dish Network and you use an FTA receiver, you will not see their programming. My question being similar, if you do not have a subscription to Salem A and you try to listen to it with an FTA receiver, would you hear anything or would it be blocked? From the answers, it appears that you can hear it just fine. That would mean that the Compel control commands only tell a Unity 4000 (FWIW, I was the one who coined the term U4K) receiver whether it can or cannot listen to a specific channel. Otherwise, the channel is not scrambled and should be receivable by any non-U4K (or other Compel controlled) receiver.
With eleven channels, I happen to be the biggest user in the CRC group. I also have two full time and one part time channel on the ABC Starguide system on AMC1.
Even us 'experts' need some help now and again.
Thanks again everybody.
