I must disappoint you here; first of all I have massive respect to Thomas Winischhofer, the developer/maintainer of the X driver for SiS chipsets, he has a well documented website on which he elaboralety describes every driver option that he squeezed out of the SiS chips. In the FAQ however, I only recently stumbled upon this:
* Q: Why does output of interlaced video via TV show a "comb-like" "interlace"-effect? If the source material is interlaced and the TV output is interlaced, shouldn't this match? * A: CRT2 does not support interlace. Therefore, the driver can't feed interlaced output into the video bridge (which handles TV output, be it a SiS video bridge, be it a Chrontel TV encoder). The video bridge can only convert a progressive scan (=non-interlaced) input into TV-suitable interlaced output. The driver can neither change this nor control which of the frames sent to the bridge is the even/odd field. Long story short: If you want to output interlaced material on your TV without using a software de-interlacer, you need to add a proper Modeline for interlaced PAL/NTSC timing (easily found on the internet) and an external VGA-to-TV converter connected to CRT1. Otherwise you have to use a software de-interlacer.
You have to acknowledge that is is a Very Bad Thing�. What I said about the interlaced material is not entirely true, but the result is still not quite useful. Damn bastards @ SiS. Oh well.
here. It does *not* say that TV-OUT does not do interlace mode. It says that
CRT2 doesn't support feeding interlace to the the TV encoder. That has nothing
to do with whether or not TV-OUT then interlaces output.
