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.
