[mythtv-users] mythpreviewgen causing high iowait

I've been using myth for around ten years now, but have recently hit
some problems that I've been unable to solve from searching mythtvtalk,
etc. I figured it was about time I joined this list, perhaps I can
contribute as well.
I'm currently running mythbuntu as it is simple to set up and just works
with minimal effort. Something that's been bothering me is that when
watching live tv and a programme ends, myth stops streaming for a second
or two and then carries on.
Using iotop I've discovered that mythpreviewgen seems to be the culprit
on the server side. During the freezes mythpreviewgen uses 100% IO
presumably when generating the preview of the last programme, before
myth starts to play the next programme. Is this a known issue? Can the
process be reniced or modified in some way to be less demanding on IO?
