i am looking to buy the pioneer sc-lx81 amp /reciever with the bdp-lx71 blue ray player would i be able to get dolby true hd & dts hd master using this set up, also is the pioneer krf-9000fd projector any good.
Yes to the first question (HD audio). You'll have to search for reviews (check the TV and projector forum too) on the Pioneer PJ. There are plenty of good projector sites on the web to help you choose one that will be suitable for your room (throw/screensize etc.).
