Well, sure.  I dont' care where I reply but I thought I would save the
rest from the chit-chat and just followup with an answer.  But
whatever, it don't matter to me.

Yeah?  Funny thing is I have some broadcast television which does not
seem to want to "detc" either.  Same effect.  2 good frames, 2
interlaced frames...

Indeed it does.  It's been sized to fit a CD so you are most probably
correct.  My guess is that it was "hard" telecined by whatever
software ripped it from the DVD.

Nope.  My DVD player doesn't do SVCD.  Just VCD.  I have played it to
television via MPlayer and DirectFB with my G400 (which preserves
interlacing) and it looks alright.

It was juddery but I just chalked that up to a weak CPU.

Any plans to make detc detect and deal with this anomoly?  In CVS yet?
I just did an update and it didn't touch vf_detc.c.

Nice.  :-)
