[mythtv-users] Watching recording causes ghost image during recording!

Hi,

Since a few days, I'm having a strange ghosting problem with my MythTV box.

Every time I watch a recorded show from disk during a scheduled
recording, this causes a ghost image in the new recording! Please see
this image for clarification:

As you can see the ghost image from the show I'm watching, is imprinted
at the bottom of the new recording. It is the same frame all over again,
for the entire duration of the scheduled recording. Also, the view port
of the current recording is reduced.

The ghosting also affects all future recordings, the only way to stop it
is to reboot the system.

Does anybody have a clue what's going on?

I'm using a PVR-250 (so no video out) on a Shuttle SN45Gv2 running
Debian lenny/sid.

Thanks for your help!
