The binary drivers have lots of additional support beyond TV-Out capabilities:

XvMC is only in the binary drivers  I believe the GF2s have (at least) MC
capability (but not IDCT, as I mentioned before that's only in the 4MX and FX
series)
Plain Xv may only be in the binary drivers (Although with your insanely low CPU
numbers it sounds like the stock drivers have Xv)
3D support is kind of irrelevant for MythTV
The binaries are usually faster in all regards

Also, turn on "extra audio buffering" - oddly this actually helped with some of
my video pauses.

Do the pauses only happen when you are currently recording, or do they happen
when there is no recording being done too?  (Once the Live TV buffer gets large
enough, it's possible that seeking between the recording write position to the
playback read position repeatedly could bring HD transfer rates below what is
needed.)
