Several months ago I submitted a patch which made the various buffers in
MythTV configurable with a number (IO multiplier) from 2 to 6 per storage
group. Depending on the speed of your system & storage, setting this to a 2
or 3 really speeds up channel changing, but can break very low bandwidth
streams like DVB radio if set to 2 for LiveTV.

I believe the ticket is still open but likely the patch won't apply cleanly
to trunk.
