there are a lot of rackmounted sdi convertors from vga out there.
to suit different budgets and different requirements.
the miranda thing is not representative.
what does your client want to do?

S-Video to SDI
Hi
Thanks for all the nice links, i got an idea. The Radeon 9800 has a S-Video out, is that supported by the Catalyst software at all or is it working just as it is?
Then i could get a relly cheap way of solving my problem. These converters are pretty common and does just what i want.
What my customer want to do is just not having loads of Coax and amplifiers since the Catalyst racks are a long way from the LEDscreen.

i have done shows where the led screens are run from the composite or s-video output from the 9800.
composite looks a bit shit around the edges, but sometimes its fine for what the client is aware of.
You just have to check.
You can output composite or s-video directly from the mac using the retail 9800, and catalyst will work with the outputs.
What you must do is actually have a video device connected to the system when you boot it up.
The 9800 cards senses the output on the composite connector, and if it doesnt see a 75ohm resistive load, it assumes no video device is connected or present, and does not give you the option of outputing composite video.

I've used some Smart-E VGA to cat5 converters - One at either end - Cheap and effective option - no signal loss. Can also send RS232 with certain ones too.
The extron VGA - SDI scan converters are great - 1U half rack size - available from good AV hire companies...
