Glad I'm not the only one - thought it was the addition of a DVB-S card
that was causing problems with my PVR150 but sounds like that is not the
case...

Note that when I hit a glitch, a rewind and replay will hit the same
glitch, usually associated with symptoms that looks like a missing
keyframe (i.e. a pixelated screen that builds up over 1-2 seconds into a
complete screen again).

Can provide logs and sample captures if required.
