bttv weirdness

Howdy:

I have a Cybertainment video email thing (with a bt878 chip) that
has two RCA video inputs and one S-Video input (but no TV tuner
stuff).  I tried to get updates to the buggy windoze drivers, but it
appears the company has fallen off the face of the planet (or at
least changed names or something).  I found some windoze drivers and
capture software that actually work okay, so I know the hardware
(bt878 card, camera, etc) works.

I have a Soyo Dragon with 1.2 GHz Athlon, 256 MB DDR memory, Voodoo
Banshee AGP, Buslogic SCSI, SBLive, NetGear NIC, and the bt878 card.
  I upgraded the RedHat kernel from 2.4.2 to 2.4.7 and all the
modules seem to load fine (see below).  The chipset on the Soyo
board is some kind of hybrid, at least it uses the latest 266 MHz
VIA chipset, but the hardware monitoring stuff uses an SiS chip.
I'm no expert, but I don't think it's a standard VIA
northbridge/southbridge setup.

When I try and run xawtv (the latest as of today), it totally horks
up the video before it even finishes loading.  Sometimes it goes
into intermittent mode, where it seems frozen, but will keep going
in fits and starts, and if I'm lucky I can get a responsive xterm
and kill the xawtv process.  But even then, fonts and things in
other windows are garbled, and I still need to restart X before it
comes back all the way.  Other times, it pretty much locks up with a
garbage display of some kind and won't respond to anything.
Videodog pretty much produces garbage.

I've been going through a maze of docs, plus searching the mailing
list archives, but I'm still lost.

Questions:

How do I tell what version of bttv is in the 2.4.7 kernel?

If I need to upgrade, how do replace the kernel bttv stuff with the
new stuff?

Should I try the v4l-2 stuff?

Are there any module options that I could try?

After a clean boot, I get:
