[mythtv-users] Question regarding video input

[Phil Bridges]

I'd like to be able to run my Playstation 2 through my Myth box.  I have 2
PVR-250s in it right now.

What concerns me is the lag that I'll have that will make gaming
impossible.  Is there a way to turn off buffering for my S-video input on
one of my cards?  Can I easily set Myth up to not use that card for
recording when it's set to S-video in?
