Just letting everyone know I found this new RFBox from radio shack that also convserts S video to coax.

Bought it last week and have used in five different gigs now. The last one had the signal split to the singers monitor and five other 35" or larger flats throughout the bar. Crystal clear signal. Further, since I'm running off computer and player for singers disks, switching back and forth with an A/B video switch box has been flawless as well and has not affected the extended desktop funtion. A nice unit to elim all the other gadgets for converting S video signal.
