Well I could defintely tell it was framebuffer
related, because when I ran X on the pundit's ouput,
and just the TV on the PVR-350, it was very stable. 
Also when it "locked", it was just the framebuffer
display, everything else on the machine was still
working fine.  However, I still can't explain the fact
that both the pundit's and the PVR-350's s-video will
only output B&W now, when prior to the 350 (with two
250's) the pundit's s-video output worked fine.  It
almost seems like a hardware resource conflict.  Maybe
this combination just doesn't work in the pundit?  I
haven't pulled out the 350 yet to verify, 'cause it's
such a PITA with this case and the slightly oversize
cards.

For the record, the two 250's worked great, and I
grepped through my old syslog's and there was never a
DMA error.

I'll try out the CVS versions of myth and ivtv this
weekend and see what happens.  I'll post a question to
the ivtv list and see if there's any thoughts there as
well... Then I'll hack mplayer to play DVD's with the
350's 720x480 output. :-)
