What do you mean by 'fully supported'? I've been using it successfully for over a year in GBPVR. I get both digital and analog channels just fine.

No tweaking needed. There are many of us using this tuner with GBPVR and in my humble opinion, it's one of the best and most recommended internal cards for working with GBPVR.
