I have a friend that's been pestering me regularly to help him set up a
MythTV box under Ubuntu. I've never set-up MythTV before, though. I'd
love to get some links, gotchas, and ideas from you guys about hardware
and software concerns.

Subject: [NBLUG/talk] Quick note re: MythTV
Just thought I'd mention that MythTV can use firewire to a
suitably-equipped cable box in the Motorola DCT-6200 series (and perhaps
Myth can change the channel via firewire (both internally, and with an
external program) -- and many channels are available for mpeg-2 capture,
including some HDTV...
The cable box will even hand you mpeg2 data for analog channels -- woot!
I broke down and bought a new workstation a few weeks ago, then
discovered that I can't use my (5V) Hauppauge WinTV card in my new syste
-- so, my old ws sits there as a slave backend. I'm using NFSv3/udp for
storage, with my new ws as the server -- it also runs the master backend
and (of course) mythfrontend. (Note that the myth docs are a bit
ambiguous on this point; they say you need to have at least one capture
device on your master backend
-- but that turns out not to be the case...
One downside to this arrangement is setup -- there isn't any way to
specify with mythtv-setup that a given tuner supplies two capture
methods. So, I have to be careful about scheduling conflicts, lest
mythbackend change the channel and start recording using (say) mpeg-2
when it is already recording with the composite feed...
However, I've been pondering the mythconverg schema, and I think it
might be possible to set up such an arrangement with a few well-placed
bits of sq(uea)l ...
Another downside is figuring out which channels are available over the
firewire -- I have some ideas for how to scan them automatically, but
won't have a chance to figure that out until this weekend...
p.s. oh btw, you can daisy-chain dct-62xx's on one firewire buss for
