Audio/video run with Cat5e

Actually I have two questions about using Cat-5e cable for A/V:

1. I have Cat-5e cables for my home telephone so there are four (two pairs)
wires unused. Can I used these four wires for S-video with Leviton S-video
Quickport (http://www.smarthome.com/865166.html) without interference with
telephone ?

2. Can I run a single Cat-5e for both S-video and audio with Leviton S-video
and RCA 110 type Quickports without any interference ?

Thanks in advance.

I've never shared a cable between a phone line and an S-Video, but I can
imagine that, due to considerable difference in operating frequencies, you
will see no picture degradation. However, it is really worth mentioning
that the ring can generate 100V potential on one of the pairs in this
cable, so you will feel much safer if you use a whole different cable for
your audio/video stuff.

S-video and stereo audio run just fine on CAT5E for just about 100 feet. I
 haven't tested further without a balun, but if you need to go several
hundred feet, you can purchase a couple of baluns (impedance matching
transformers) for both ends of that cable, and send the signal without any
quality degradation on 500 feet or more.
