The problem with the KT133 chipset has nothing to do with bttv.  If you 
have a bttv card, as you seem to, then there is no issue.  The problem 
occurs if you have an ivtv card (PVR-x50, M-179).  There is a known 
chipset bug (or 'quirk', if you prefer) that causes problems when using 
the ivtv driver.

Incidentally, Myth does not use 'bttv' for playback... since 
playback-only in Myth doesn't involve the tuner card.  The bttv/V4L 
driver is only used in Myth for recording or LiveTV.  Playback is done 
solely through your video card using X (Xv/XvMC).  So it is entirely 
possible for problems to arise during recording that don't occur during 
playback only.

Craig was only offering a helpful suggestion... there was no need to be 
rude, especially since it seems you're not really clear on how Myth 
actually works.
