I've currently have 2 RG-6 coax and 2 CAT5 cables running from a central distribution box to every conceivable location I would want TV, Audio, Computer, etc. I also have a pair of fiberoptic cables bundled in with the cable for a couple of rooms.

I would prefer to send video via S-video and audio via optical, but I'm not really sure how to do it. I also am not sure what the best approach would be for relaying the IR signal for remote control.

Can you use CAT5 for s-video and if so, where can I find the terminals and crimping tools?
Are there affordable tools for crimping toslink-type connectors to fiberoptic cable?
What's the best way to control IR devices from other rooms (X-10?)?

Since the drywall is going up in my basement beginning in October, I would like to run any cable I need soon.

Thanks for the input!
