In addition to my questions above I want to give a sample command
showing the error:

mencoder dvb://1@ard -o capture.mpeg -of mpeg -mpegopts format=dvd:tsaf
-oac copy -ovc copy

Attached you find the channels.conf and the mencoder.conf

Additionally, I tried some regression testing (cf.
http://www.mplayerhq.hu/DOCS/HTML/en/bugreports_regression_test.html) 
but without any luck. I cannot find any checkoutdate with some source
that compiles. All the stuff I check out since Jan, 1st 2011 fails at
different points. I tried disabling a lot of mplayer features for a lots
of days. 

Since I'm not a developer I'm a bit frustrated now:

1. With current releases dvb-capturing isn't possible anymore for me.
2. I'don't find a compiling releasedate for regression tests.
3. I don't get any response to my questions above.
4. I don't find any information in http://bugzilla.mplayerhq.hu 

Am I actually the only one with the dvb-capturing-problems mentioned
above? If so, what am I doing wrong? Is this the correct mailing-list?
If not, please tell me where to discuss the problem. What am I doing
wrong with my regression tests? What is the needed setup to quickly
compile and test different source stands?

I am stuck. Please help.

Thanks
