S-Video gives a higher quality signal than composite. Whether this is
discernable will depend on your source, but given the choice between
the two, go for S-Video.

Either of the above choices would be good and are well supported by mythtv.

The generic linux 'nv' graphics drivers can be a bit 'sucky' for
mythtv. The alternatives (nvidia, unichrome etc etc) are chip
dependendent so may not be suitable for all motherboards.
Motherboards using the nvidia 6150 video chipset seem to be popular as
'on-board' graphics drivers for myth systems.

In theory there shouldn't be much difference between HDMI and VGA.
Some TVs handle the VGA and HDMI inputs differently with regards to
maximum resolution, overscanning etc.
I'd be very suprised if you could send audio down a HDMI cable. How
would it get through the graphics card?
