I got an email back from my JVC dealer a minute ago...
This LoLux was a betatest a while ago which worked with minimum gain of 24dB, but the image was too noisy and not suitable therefore for professional usage. Bummer...

Well, this makes no sense in light of that article in Studiodaily.com. I'll admit the thought of shooting anything between 24 and 42 dbs of gain is unsettling.
Is it possible the HD200 line (with the 18x lens) was accepted by Discovery HD without the LoLux firmware? Is it possible the article is flat out wrong?
Questions, questions...

They're not sure they'd allow use of the RED One? C'mon, 4k progressive is good enough for Peter Jackson but not a relatively obscure HD cable station?

One visit to Discovery's headquarters near the capital and you'll get a sense of who they are. First, they encompass many networks, among them some of the more popular on cable/satellite:

Discovery
The Learning Channel (THC)
Animal Planet
Travel Channel
Discovery Health
Discovery Times
Military Channel
Discovery HD Theater

And there are no doubt a couple I missed.

The building that houses all these networks is nothing less than incredible. You really can get lost in it. By comparison, National Geographic Channel for instance is a log cabin.

Their engineering department sets the standards for all of the above channels, but I understand that rather than reinventing the wheel their work provides standards for other cable channels.

I went through hell and perdition with them because they wouldn't accept my JVC D-9 format KY-D29 2/3" 4:2:2 camera even though they accepted lesser DV format cameras (standard def days). JVC even offered to provide them with a deck to eliminate that possible objection, but they never accepted D-9 (aka Digital-S) which is identical do DVCPro50 but with a 1/2" and therefor more robust tape.

Can you blame Discovery for not being willing to COMMIT to accepting a format that isn't even released yet? The article says that their engineers put the new techologies through field production tests first. RED will be no different. I'm 99.9999% sure it will pass, but lets face it, NO ONE outside of the RED camp is using them yet (and they have no set release date as of yet, either!)

OK, I received a return email from Michael Grotticelli, the author of the Studiodaily piece. Unfortunately, he couldn't answer too many of my questions and couldn't provide a link to the Discovery HD's newest guidelines (they keep those mostly private).

But he did say that on-camera interview type shows are acceptable for our cameras for D-HD, but they prefer 1080i for programs where outdoor scenes are prominent. That still doesn't clear up the picture. We can't shoot many scenics?? I find that a strange requirement. And I take it he meant 1080i from bigger chip HD cameras.

Oh well, what the heck. We still have kick-a$$ cameras.
