This is a very informative post, but I'd like to stress a few points.
Most discussions about switching from TiVO HD/3 to MythTV assume that
you care only about Over The Air (OTA - Antenna) channels and *basic*
cable channels. Typically, the only HD channels considered basic are
network channels like ABC, NBC, and the like.
If you have Cox and like all of the new HD channels that have been
added, then MythTV *cannot* be used to make direct recordings of those
channels. That's because any 3rd-party (non-cable box) tuner needs both
Cable Card support *and* support for the external SDV tuner. The only
choice for this is the TiVO.
Brian mentioned a workaround if you are willing to work with some
limitations. The Hauppage HD PVR by-passes all of the tuning issues and
just does an analog capture from the component output of a cable box.
It then re-encodes the analog output into digital form and passes that
along to MythTV or any other PC-based DVR.
There are two downsides to the HD PVR analog capture approach. First,
it can only record one thing at a time since it's using an IR blaster to
change channels on the cable box (plus, analog capture) . Second, there
is going to be some degradation of quality in the re-encoding to
digital. How much is debatable. AV forums like AVS are full of threads
of people absolutely hating the quality... but they tend to be more
extreme than most. YMMV.
There's also a cost issue. The HD PVR is $200. Tack on the cost of
building a Myth box and you're pretty close to the cost of a TiVO +
Lifetime service. MythTV is infinitely more flexible, of course, so it
might be worth it.
