Sure.

Yeah sure. I will update the ports in my svn repository to 0.22 today and
fix a few rough edges so we can do a call for testers soon.

There are very few fixes that would make sense upstream in their current
form. The biggest one is to fix the Qt3 style includes and i've already
found a developer that will do a review of the patch and commit it.

That patch is already known to the developers.

Don't know if that is the best way. I will have a closer look at it later.

I have no supported card so i cannot test mythtv backend on FreeBSD and
would appreciate it if anyone could test functionality of mythtv. Frontend
is easier to test for me and i will try to upgrade my linux box with the
backend this week.
