My first and final attempt to help out in the Mythtv "community", was when I signed up to their forums and posted a follow-up to an existing thread. My follow-up quoted a few lines from an earlier posting by somebody else, which happened to include a useful web link (from the quotation) to some patches or something.

I got "banned" for posting links as a n00b, and my IP address got blacklisted. Lovely people there. The funny thing is, this behaviour turns out to be about 100% typical of their closed development "community" and active hatred of end-users.

End of story.
