I posted some steps in the MythTV wiki for the HD-PVR.  http://www.mythtv.org/wiki/Hauppauge_HD-PVR  These steps should get most people up and running.  It does require compiling drivers - if you're not comfortable doing it then something like Fedora (already includes IR support) may be a better option.

Well, that would be a bummer.  I actually looked a little closer at
the box I am trying now and the model is a DCH3200, not a DCT3200.  I
don't see any mention on the codeset page of any DCH models, so maybe
it is too new or something.  I think these are pretty standard boxes
for Comcast cable, though, at least in my area.  I think I may have on
other older box that I can try, although it will take some juggling
around.

If there are any other suggestions they would be greatly appreciated.

Thanks,
John
