I bet you'll get better quality from S-Video because that way you use
the TV's deinterlacer. If your experiences with S-Video were less than
perfect then make sure that you are using 720x576 (for PAL) 720x480
(for NTSC), that you have no scaling (do not scale to undo the overscan
- except for menus; I'm assuming you're using MythTv). Turn off
TVDeflicker in your xorg.conf. Don't use a deinterlacer.
