Already done. :) I actually modified the SVCD module so it is
"MPEG2" export with an [SVCD/DVD] prompt and a frame size prompt.
This allows export of SVCD/CVD/DVD compliant video from that
module.
I was just testing it heavily (25 episodes of childrens shows) when
you put out the reworked nuvexport. I'll rework the support into
the new framework shortly. Well, as soon as I meet the family's
backlogged demand for exporting shows out to DVD.
BTW, if DVD is selected I default to half D1 (352x480) because the
starting source is poor (broadcast) and my goal is to get lots of
episodes per-DVD. At 352x480 and 4000kbps video / 224kbps mp2,
I get ~3.5 hours per DVD-5 media. The 4000kbps is a little high
though, 2500kbps-3000kbps should be plenty adequate for better than
SVCD quality (considered the smaller frame size) yielding 4+ hours
per DVD-5.
