I am a video producer/editor at a graphic design firm. I use an sgi O2 with a/w composer 4.0, but that's not necessary to produce dvd's. To produce a dvd, all you have to do is locate a duplication/mastering house in your city. Most larger places have dvd capabilities. We end up sending either a betacam sp tape, or a dlt tape.
The O2 captures and outputs uncompressed video frames in real time. When the video is rendered, it is a simple matter of just copying the files to dlt, and sending them on their merry way. Depending on the production house, they might ask for certain file formats, depending on their mastering equipment.
The cost for all this isn't bad, they usually charge per minute for encoding, and then a fee for the master disc. Additional discs are quite a bit cheaper after that.
Good luck!
M$ is more likely to see Linux (and BSD) as a threat to its market because of architecture. Windoze started on, and will probably always be on ix86 architecture. Linux runs on ix86, PPC, and pretty much everything else there is for that matter. MacOS runs on 1 propriatary hardware platform...
Let's face it, Macs are expensive, ix86 is hillariously cheap. That's what it usually boils down to. Buy a Mac for $1600, or buy an Athalon for $700. Hmmph. Seems pretty straight forward... And, have you ever tried to shop for Mac upgrades, periphials, etc? Add that to guerilla tactics, and you can see why M$ is popular. So, to really be a threat to M$, you have to play on their field.
I still use MacOS every day, but only out of necessity. I am a graphic designer. I used to be an avid Mac supporter, not anymore. Whenever I can, I use my Linux box or SGI, depending on the application. I can't stand the limitations of the Mac environment. Add that to the terrible instability, and you can see where it is going. Hopefully, OsX will be stable.
I didn't know that M$ employees were allowed to post to slashdot on company time... shame shame I've heard of hard sells, but this one takes the cake. Next you will be telling us that Micro$uck will protect our children from the plague. Get real.
It all depends how much of an offset (if any) is between the send and recieve channels. It also depends on the bandwidth of the channels. When you're talking microwave, the bandwidth is (relatively) small. Therefore, you can have both signals passing through the waveguide at the same time without interference. Radio waves don't "run into" eachother.
The other possible scenario is that both channels are multiplexed travelling on one carrier (how do you think a phone line works full duplex on 2 wires?) I can't confirm this as I don't know the specifics on this card, but it is done quite often.
You should consider doing some research next time...
Putting a computer on the mast is not a great idea. Although it can be done, it costs quite a bit for a reliable solution.
Depending on the frequency that the wavelan cards use, you can use something the microwave industry has used for decades: Waveguide. Basically a small duct with a transducer on one end that passes the signal through the waveguide on a shielded path. The waveguide is usually sized to the frequency of the transducer. Check some of the microwave ham radio pages out there. Waveguide is usually used in the 10ghz+ spectrum.
Another approach is to use a mast mounted amplifier and pre-amplifier and use a short run of 50 ohm hardline. This is what a lot of ham radio users use for high performance antenna arrays in the uhf and microwave spectrum. Basically, you keep your computer in your home, and run a length of hardline to the mast mounted amp/preamp. The signal losses incurred by the cable are overrun by the mast mounted goodies. By doing this, you can mount your antenna directly to the amp/preamp and have no loss.
