Xv support - failed

when i select 'watch tv' in myth i get kicked out with this showing:


Changing from None to WatchingLiveTV
Over/underscanning. V: 0.000000, H: 0.000000, XOff: 0, YOff: 0
Couldn't find Xv support, falling back to non-Xv mode.
* MythTV performance will be much slower since color
* conversion and scaling will be done in software.
* Consider upgrading your video card or X server if
* you would like better performance.

when i type xvinfo:

...and on for a few more pages

anyway, are there myth settings that are causing problems for xv
support?

It's your video (output) card that needs Xv support. The only
thing you've shown up there ("video4linux") is your capture card. You
need to have another adaptor listed for your video card like this:

Adaptor #1: "NV10 Video Overlay"
or
Adaptor #1: "ATI Radeon Video Overlay"

********************

where exactly is this added so that it shows up in xvinfo?
i've got an nvidia card so i'm assuming nv10 video overlay.
just not sure how to make this happen.
