MythTV again...

I have been using MythTV on my FreeBSD machine since, well a very long
time now, all the way back from when I assisted usleep with making the
necessary changes to MythTV in order for it to work with FreeBSD.
This setup has worked so well that I haven't even bothered to upgrade
neither tha machine nor the driver (cxm) or MythTV.

I'm still running on the same amd64 machine, still with the same
PVR-500 tuner card, and still with this setup:
root at kg-fil# uname -a
FreeBSD 6.2-STABLE FreeBSD 6.2-STABLE #20: Mon Mar 12
23:04:49 CET 2007     root at

The PVR-500 has dual tuners, allowing me to record one show, while
watching LiveTV, or recording two shows at once. And still watching
recordings. I'm using a Macmini (G4) with Mythfrontend as the frontend.

However, this evening I was watching a few episodes of Heroes, and
after I finished one episode, I can't get the frontend to start
playback of _any_ recording at all, not even the episode I was just

If I start Mythfrontend locally on the backend, it works, and I see
this in /var/log/mythbackend.log:
2007-10-09 22:16:00.469 MainServer::HandleAnnounce Monitor

When I start mythfrontend on the Mac mini I see this 
in /var/log/mythbackend.log:
2007-10-09 22:21:33.488 MainServer::HandleAnnounce Monitor

2007-10-09 22:22:10.644 adding: torfinn-ingolfsens-mac-mini.local as a remote file transfer
Mutex unlock failure: Operation not permitted

Any clues on what can be wrong?
AFAIK, I haven't changed anything on neither the Mac mini or the backend machine:
Torfinn Ingolfsen,
