Hello again, I found this ticket: http://code.mythtv.org/trac/ticket/9177

It is solved, I am on the debian-multimedia repository's squeeze
version (0.24+fixes20110121-0.0), which version recomended to get this
patch?

I never compile mythtv from trunk, I like Debian apt-get software, I
try with apt-pinning but I have lots  dependencies problem. I will
wait to Marillat (repository own) to update the version.

Regards.
