If you pull down stoth's cx23885-video tree, you can enable the mpeg2 hardware encoder, and then you'll have analog mpeg audio and video fully working .  After some more testing and cleanups, that will eventually be merged into the master branch.

At least, at this point it seems I know more than Comcast does about what a "tv tuner card" is and what it's capabilities are, and this is what I've figured out so far.

Since I use Time-Warner I can only pass on what I know generally. If you 
have a digital subscription the contents are (a) NTSC analog, (b) CATV 
digital, and (c) over the air digital. When I got my first TV with 
digital broadcast capabilities I had not upgraded the cable box in the 
bedroom, and I was getting HDTV and standard TV digital on the cable 
without a box.

Since you mention cost, at least with T-W the digital converter is the 
same price as the analog, there was no increase, or I can run with no 
converter and just get the CATV analog and/or broadcast digital at every 
cable drop in the house.

> So...Mike or anyone out there, I need a simple roadmap of what to do next.  If I want to try SDTV, for example...where do I start?  Otherwise I'm thinking I'll just put it in the box and wait for a year or two.  :-)

I would check pricing very carefully, to see if you can just change to 
the digital plan and not get a box converter. Don't assume it's bundled.

Second, borrow an old set of rabbit ears and *try* the signal on digital 
broadcast. Radio is limited to 50kw max, while most TV stations run 
200kw or more, giving you at least 3db more signal. The broadcast is 
amazing, in addition to five networks[1] in NTSC and HD, I get weather 
and alternate content from most of them, and some alternative 
programming like ION network, with several levels of content.

Don't assume any worst cases without testing, I was totally amazed at 
what came over the air and what was on the digital cable I didn't expect.

[1] ABC, CBS, FOX, NBC, PBS. Also ION and whatever is called C-W.
