Unfortunately i think i can't be specific enough. I have disortions 
(glitches, klötzchen?) on live view and some stability problems 
(computer is freezing without any message). With one card (TT Rev. 1.3) 
the live signal ist interrupted with a black screen. If i record a 
stream with this card the resulting recording is fine. This affect only 
live view. The same card works with Kernel 2.4.x and the latest DVB 
Tree flawlessly.

Other users report various diseqc problems wich i can't reproduce 
because i have any diseqc equipment.

What a pity. Thanks for trying anyway...

I'm using Kernel 2.4.5 with the latest dvb-kernel from CVS.

Of course, and i enjoy your work on the dvb driver.

Yes, you are right. I don't want to offend anyone.

As i said, from my point of view the latest changes are quite 
confusing. Two (or three with API v4) trees with multiple branches for 
several Kernels... DVB, dvb-kernel, HEAD, REHEAD... sync 2.4 and 2.6, 
now an own 2.4 branch within dvb-kernel side by side with the DVB 
tree...
