[mythtv] weird pdflush & NFS problem

I have been having some issues with MythTV - whenever it is recording
a hi def show and playing something back at the same time, there are
pauses every 30 seconds or so.  These pauses happen when pdflush wakes
up to write out the disk cache.

Does MythTV have an option that works the same way as mplayer's -cache
option?  I thought that the ringbuffer setting would be the same.
Obviously it isn't, because MythTV is pausing instantly once the NFS
server decides to take a break for a couple of seconds.
