Edgar-

I have seen your patch, and I can't say that I disagree with you. 
Remember, I applied the v4l portion of it to video4linux cvs.  However, 
Manu knows a lot more about bt878 that I do.  As far as the dvb-kernel 
portion of the patch, Manu has made comments to you about it and you 
have yet to respond to him.

http://www.linuxtv.org/pipermail/linux-dvb/2005-September/004492.html

Please, follow up with Manu about this and get him to apply it, or a 
modified version of it for you.  You will have to regenerate your patch 
against current cvs, of course.

Your patch has helped Lukas with his PCTV Sat card, and it would be nice 
for you to take Manu's advice on these changes, before we apply them.
