I actually do need the latest v4l drivers. My 1st
card is a DVICO FusionHDTV5 RT, a conexant card, and
which is only supported in the latest repositories.
Perhaps, instead, the mythtv developers might be
persuaded to update their support for blackbird cards?
As far as I know that's my only solution. From my
perspective, the mythtv software is all that's holding
my system back.

In principle, this sounds fine; however, as stated in

This sounds like the freezing problem I described in
the wiki, although
don't recall it happening except after a channel
change. (It's been a

I just checked my log file and I see a bunch of error

Definitely not. I've got two non-IVTV MPEG-2 cards
(well, one card and
device) on my MythTV system.
That said, my understanding is that the API used by
the IVTV drivers
universally supported, and that there's another API
that's now being
most drivers. My very limited understanding is that
MythTV still uses
IVTV-specific API. It's conceivable that the Blackbird
support for the IVTV API. This could be causing some
but it shouldn't be causing total failures, AFAIK.
I've tried to learn
about this, but I couldn't find any user-oriented
documentation on it

Check the wiki; all that information is there. I think
to using a too-recent kernel (or blackbird driver from
the right kernel driver version, it works, albeit with
quirks. With the
driver version, it's completely foobared.
Unfortunately, newer is not

tried 2.6.21 at
point, and I definitely tried more recent
out-of-kernel drivers). The
126.96.36.199 kernel is certainly not "current" by Linux
standards, but it's
yet so old that it should cause you problems to use
