Okay, I've pretty much got the jist of h.t. techs but when it comes to computers I'm still totally lost.... I'm buying a Plextor PX-716UF external DVD-ROM burnign drive this weekend and want to set my office up for movie watching. My coputer's an Intel Pentium III (Windows XP) and I've got a Samsung Syncmaster 173P 19" LCD hooked up. It's got DVI input and I'd like to take advantage of that. I haven't even had a regular DVD-ROM drive on my computer so I've never actually been able to watch DVD's on it before, but I;d like to set it up for the best possible quality I can get out of a pc connection. I don't really know where to start. Are there certain codecs and video cards and stuff like that I need or should look into picking up? How do I run DVI through for HD signal? Will this involve many cables and wire connections and what else is reccommended for a good movie-watching experience on my pc? My office doubles as a guest room when friends/family stay over, and because of the available space, I don't really have the room (actually I probably do but I dont want to sacrifice it and cludder MY space) for a TV or standalone display device. I don't even have television connection yet, no cable plan or satelite. So I'd like for my guests to be able to watch movies on my LCD monitor at night or whatever, if they're using the room. It probably won't get used often for this purpose considering I've got a state of the art projection setup in the living room a few feet away and my bedroom is next door which will eventually have a plasma on the wall when it becomes affordable, but I still want to be able to get the maximum performance from DVD on my PC regardless. If anyone could guide me through the main steps and keep in mind that I'm somewhat illiterate on the technical side of this, it would be greatly appreciated. Thanks a lot!
