Two coupon-qualified boxes that DO have S-Video out are the Channel 
Master CM-7000 (generally reviewed as the best box, period), and the 
Apex DT-250 available at Best Buy.   Both these boxes also have the 
Smart Antenna control output for automatically-steered active 
directional antennas.   The Channel Master is typically $30 after 
coupon, while the Apex is only $10-20 after coupon.  

Another one of interest is the "Airlink 101" which is only $40 and is 
net zero after coupon. Although it doesn't have S-video out (only ch3/4 
RF and composite), the real attraction of this box is that it's chassis 
actually operates on +12VDC via a wall wart with the same coax power 
connector used on TNCs.   Connecting this box to a laptop with analog 
NTSC video-in, or a 5" DC-capable TV, gives you a DTV receive setup that 
can operate on emergency power from a ham station's 12VDC battery plant.

By the way, all three of these boxes have analog passthough.
