Govo,
Select computing on the Linuxmce menu->
capture cards->add new card->switch pvr 150 v4l to mpeg2->
sources->add source for cable provider->
connections->select tuner 1->select your provider->scan for channels
I was trying to save some money and chose the pvr over the hdhomerun, but after the picture quality issues and lack of power supply to add the pvr150, instead of buying a new case/power supply i might as well just get the hdhomerun with dual tuner. just a suggestion.
