    Complex Question

    there are HDMI and DVI "extenders" that convert the video into (generally) two Cat5/6 cables. But this is not ethernet, and doesn't go through regular switches and hubs, but only directly to a matched "receiver" at the other end. There are a couple of ways of doing what you're looking at...

    Best ceiling mount for drop ceilings?

    as you may have noticed, there are countless mounts out there. Even if you subtract out the ones that, for various reasons, are unsuited to your projector, there are still probably hundreds that.. are. Likely one of the best things to do is answer a number of questions. Not that we need to...

    Speakers behind black out cloth screen?

    There are other materials for "home brew" AT screens; I've made a variety over the years, to more-or-less success. If you're doing a permanent installation -- as in, the screen doesn't need to go away when not in use -- then it's not hard. Granted, a DIY acoustic-transparent screen will be...

    Wuold like some opinion on placement of some diffusors

    Interesting; I hadn't seen diffusers over absorbers before.

    I would pay $100 to $150 for a truly complete saga that includes the Original (original un-altered,

    I suppose you might get into some purists asking, "what's original?" Some would say the original release without "A New Hope" at the crawl. And particularly with SW:ANH, it sounds like there were 4-6 different audio mixes in circulation. That said, if I could get a clean, HD version (not an...

    The Rocketeer Blu-ray available for preorder on Amazon

    sometimes, a film has a certain sort of "feel." And some of the best action/comedy films are the ones that it feels like everyone on-screen is having a good time. This, and the, what, 1994? Phantom are two of my most obvious examples of the cast having a ball with making the film. This is one of...

    Yamaha DSP A1 - no sound on main speakers with surround hooked up?

    I may have to go back and check ... I think I bought a Service Manual when I got mine, and I sort of had the impression that the five primary amplifiers were all independent sections; the only ones really "ganged" were the two front effect channels. But then again, I don't trust my memory much...

    Yamaha DSP A1 coupler links

    if you're more adventurous, my recollection is that they're only coupling the center-pins. I can't quite remember the AWG, but you can make your own simply out of either #8 or #10 copper wire. I suspect it was #10, 'cause I don't think I had any #8 lying around, but it's just about the size of a...

    Which Plasma to buy?

    another point on plasma burn-in. If you keep the brightness and contrast "reasonable," it's not a significant problem. If you run it in "torch mode," like you might find at a big-box store, well, that's different. I once heard a number for a brightness measure off of the screen, but I don't...

    Problem with a Yamaha DSP A1

    Carlos, it's not quite clear to me, but... ...you can get some (but not all) speakers to work? ...if you plug one speaker at a time in -- for example, front-left, into front left, and it works. Unplug, and then connect front-right to Front-left. unplug, and then put the center into front-left...

    Bulb Exploded ..

    The first time is always the worst. Actually, come to think of it, I've only witnessed it once, and it actually wasn't that bad. Fortunately it wasn't one of the 1.2kW xenons! Most of these lights contain a trace of mercury, as well as some thallium-204 (radioactive, poisonous, see...

    UHE (E-TORL) bare bulb polarity?

    the only place I'm familiar with the high frequency AC is during the initial ignition phase in a Xenon arc.. where they ionize the xenon by pumping it with several megahertz HF, HV, no current, before blasting it with the high current DC... I'm not familiar enough with these "tiny" lamps...

    UHE (E-TORL) bare bulb polarity?

    Hm. Interesting. I know xenon lamps are polarity sensitive -- DC arcs. I kind of suspect that the smaller lamps are DC arcs, but I don't know that for certain. While I am not an expert, however, I offer this suspicion: if the polarity matters, and you get it wrong, a. the light...

    Battery power for my plasma TV?

    "reasonably," no. In actuality, you can get battery back-up systems that can last long times under high loads. (Worst I heard of was to be able to supply 100,000w for 20min.) Leo

    Why do I see so many artifacts while watching STANDARD DVDs?

    I'd speculate that it's the player at fault. Can you turn off SD Upconversion on the player, and let the monitor handle it? Leo
