Have you tried:
-----
Extra audio buffering

Enable this setting if MythTV is playing "crackly" audio and you are 
using hardware encoding. This setting will have no effect on MPEG-4 or 
RTJPEG video. MythTV will keep extra audio data in its internal buffers 
to workaround this bug.

Don't know if it would help with DVB, but that's the exact same symptoms 
I get with my PVR-x50's and it fixes the problem for me.
