[QUOTE="jcee, post: 6605, member: 10506"] Giving some answers myself (hope somebody else will add usefull stuff here too!!) I have three MPEG2 Codecs on my system: -Intervideo DVD (comes with Intervideo DVD Player) -Intervideo nonCCS Hauppauge (comes with PVR 150) -Elecard Still the question: Which codecs are manipulated by MP? looking at the registry I can only see ONE key changed to "1" on ONE codec (DXVA=1, HWMC not set) I am confused now, which is the preferred codec and WHY. As far as I understand not all codecs can utilize DXVA. Is it worth spending $20 on buying Nvidia DVD codec (which is announced to support DXVA)?!?!
