setting up home media center

31 CE forumz and I'm not sure if any is the right one. I was reading an article over at the register on the proposed CSS rules and in the comments (http://www.reghardware.co.uk/2007/06/25/dvd_ripping_kaleidescape/comments/#c_26422) one of the folk said he had his flix on a NAS. So, my question is this. I do not want to watch my movies on a computer screen if for no other reason than the screen is 17" and chair is not conducive to long term use. Is there any where one could find how to set up a home theater network so one could play one's movies directly from a NAS instead of needing to swap discs all the time?
My Pannasonic DVD-51 is picky about discs and I want to be ready for Sept 2008 or whenever DigTV becomes a reality in the Peoples Republic of George. I currently use a Toshiba 32" CRT which does not handle HDTV, but I have plans...
