3 hrs later, rained out, or in as the case may be. 43-05 is building
now, with lots of traceing turned on to see what sorts of grins I
might get out of it.

No one has commented about the loss of video in the tvtime/pcHDTV-3000
card situation, am I on my own, basicly reverting to the
pcHDTV-2.0.tar.gz stuff to overwrite the kernel stuff?

------

2 friggin hours later, I'm finally rebooted. I start heyu in my
rc.local file by launching a series of scripts to set that all up,
and my cm-11a interface decided, for the first time in a couple
of years, to not talk to the 'heyu setclock' command. Boot hung,
but not of course until I'd used up half the boots per fsck on
100GB of disks. Grrrrroooowwff.

Anyway, now lets see what works.
tvtime doesn't, even if I re-install the drivers from the pcHDTV-2.0
archive. No video, just a blue screen, sound so-so.
kino works
xsane works
spcagui works

But, I did get some odd stuff in the logs while doing this as I had
a lot of traceing stuff turned on over and above the defaults:

--------------------------------
There are several sets of duplicate entries above, and to took
the liberty of clipping some of them back out, almost as if
the logging got stuck in a loop.

But, I only started kino once. And switched it to capture mode after
starting, once, and shut it down once.

And, as far as getting video from the camera and displaying it on screen,
that was fine ANAICT.

Make of this what you can. It certainly looks unusual to me.
