I am looking to use my pc as a very basic PVR which I can push my cable or Freeview signal through, save the clips to a share folder on my PC then using XBMC push the recordings via lan through to the plasma in the living room. I know this can be done, but which TV card should I use? Im not fussed about sound quality, but the picture needs to be reasonable. Also, if possible I would prefer it to be as cheap as possible. Also, Can I use a TV card to save my mini-dv tapes to my HD??
