I found some dead-end threads talking about this. Is there currently anything out there that will stream live, unbuffered video from the DTivo tuners? If not, does anyone know of any ongoing projects that are trying to accomplish this?

Thanks,
SJTD

Is it even possible to directly read from the video devices, nab the mpeg stream, and say run a process that would act as a 'mythbackend' for mythtv?
I have 2 DSR7000 directv tivos right now, and would -love- to use them as mythtv video sources, so as to avoid the digital>analog>digital conversion and all the line noise/cpu power involved. I would personally like to get a 4 tuner mythtv setup running.. has anyone checked into what this actually would take to happen?

It's disappointing that there's so little noise about this, even if it were some of the experts (AlphaWolf? rc?) saying, "Yeah, we've looked into that, and it's pretty much undoable."

If I could turn my boxes into basically just smart tuners, I'd be so happy. Just this side of DirecTV-releasing-a-PC-tuner-PCI-card happy.

Something along the lines of this (http://alt.org/forum/index.php?t=msg&th=115&start=0&rid=0&S=2a936de99bd80144fead9086a910ce75), though that project was trying to intercept reads rather than writes.

No telling how far off this is, but at least they're talking about it


The two companies also plan to collaborate on the development of a PC tuner that would enable DIRECTV customers to enjoy the high-quality digital DIRECTV entertainment experience.

Very interesting. Sorry I didn't include you in the parentheses, Jamie, no slight intended. :) I am sure to have more questions as I dive in. Every year, my professional software development path takes me further and further away from the lower level languages (not to mention the hardware).

Niiice. Course, DirecTV's involved, we can expect that, what, 2010, with oodles of DRM embedded. I would feel a whole lot more at home and able to contribute to a community like this, though, if it were a PC I was banging on.

Hmm, after reading the article ... later this year (I'll believe that when I see it) ... and a 'Viiv' initiative, IE, DRM in the processor. Wee, fun.
