Thanks for looking into this for us. I can't say that I understand all
that, but I'm glad to see that you'll help us out with a patch. A
couple of Nova-t 500 users in Melbourne were about to give up on the card.
Any idea why this card/chip is sensitive to this broadcasting problem?
Other cards, STBs, and tuners in TVs don't have any problems with these
channels ... it's only this card.
If I knew how to describe this better, I would try to let the
broadcaster know that they can fix the problem. Did you get any
specific details that I could pass on?
