Yes, including dtvsignal.  One thing I did while I was still running 2.6.6
and trying to find the problem was recompile the tools.

Yes, these: http://dl.bytesex.org/patches/2.6.7-1/patch-2.6.7-kraxel.gz
They didn't apply cleanly, but only two failed and one was because of the
version number in the kernel Makefile.  The other was tuner.c and that one
required a few changes.  I'll send a patch in another email.  There were
also a couple of fuzzies, but everything seems to work as well as when I
was running just the pcHDTV patches against the vanilla 2.6.7 (no kraxel
patch).  Mind you I haven't tried Myth at all yet.  I was hoping to get
the PVR-250 MCE working first.  I have had either the pcHDTV or the 250MCE
working but never at the same time.  Using ivtv ck95c now, but I am still
testing.

I'll post in a separate email.

Same here.  It is fun to tinker, but at the same time I want my cake and
eat it too.  Good thing we are in re-runs now.  I would *really* be
motivated if there was new HDTV content playing right now.  Of course I
have had my pcHDTV since Sep last year I think.  Well I ordered it
before it was shipping anyway.  It has taken me until the last month or
so before I started working on it.
