[mythtv-users] prebuffer underrun issues with DVB TV on MythTV 0.22

[Paul]

I'm having constant issues which  stop/start video issues with current MythTV 0.22 (atrpms)
Is there a list of things that I can check..

I'm using VPDAU with Bob on a Nvidia 190.32 ( VGA=8400 GS)

Some recordings seem worse than others eg PrimeTV
