[Openchrome-users] Mythtv color adjustment

[Lasse Nisted]

Hello again

I see that the developers are quite active on the mailing list,
and I know I can't expect them to answer every single question.
But I was wondering if I'm supplying wrong information, invalid
bugs or something like that, since no one answers.

Of course I understand if you're busy and such. This mail is
NOT meant to offend anyone or seem irritated. It's only because
I want to know if I'm doing something the wrong way.

I'm very impressed by the work put into these drivers :)
Thanks!
