Mike,
A quick marketing tip. If those "cheap old lawyers" are regular clients, buy them an inexpensive ($30-40) DVD player.
1) You save a big investment on a dead media
2) You save $ in time to dub or convert
3) You can demonstrate the improved quality of DVD and a convience feature the lawyers would like - the ability to set chapter points at key areas of testimony for quick access without fast forwarding or rewinding.
4) MAJOR BROWNIE POINTS!

Good luck

Mike

So they actually don't record an S-VHS signal....?? They're just VHS decks that can read S-VHS..? That's no good, I actually need a deck that records in S-VHS. Are there still any real S-VHS decks left?

This is what is says about the JVC SR-V101US
"....The SVHS format gives twice the quality of standard VHS and this machine can record the high quality on standard VHS tapes, no need for expensive (and hard to find) S-VHS tapes..."

That sounds like it records S-VHS to me.
