2.2.2-Release with 2.2.2-Stable applied.

No, just a AMD K5 133.

Not sure hear, the driver was detecting Temic PAL. I guess I may have
to peel a label off the tuner to find out. I had used
the driver override to set it to TEMIC NTSC, and that
seem to work part way, although yesterday I notice that it
would display under video in, but the tuner section wasn't working right
(just static)

I'll do this, and then get the Fxtv-0.46.
