Hi Stephen and everybody,

There is indeed a problem with group mythtv. 

Christian Marillat, the maintainer of the MythTV packages on deb-
multimedia.org, told me that his scripts don't create a group "mythtv".

But this group exists after installation on Debian, but I had to add manually 
user "klaus" to the group "mythtv".

As mythtv did not work, I did "apt purge mythtv*" to rebegin everything from 
the scratch. But I only could reinstall mythtv after deleting the group 
"mythtv", as Christian told me. Otherwise installation was impossible.

Copy for Christian, he will tell us if I am wrong.

There also is a problem with "mythtv-status". It was not easy to install it, 
finally I succeeded but I don't remember how.

So I reinstalled mythtv entirely and I added user "klaus" to the group 
"mythtv". But it still does not work.

Total Disk Space.: Total space is 7.1 TB, with 1,630.9 GB used (22.4%)

Are there people here who use MythTV under Debian and who can tell us if it 
works?
