Well, it appears that I finally got it working!

I made two changes, so I'm not sure which "fixed" the problem:
(1) removed the pullup,softskip from the video filter chain[1], and
(2) upgraded to mkvtoolnix 2.0.0 (not from svn though).

I still need to do some testing with source material that actually
needs -vf pullup,softskip.  Wish me luck...


Here's my quick'n'dirty script, for anyone who's interested.

# assuming the episodes you want are titles 1--4 on your DVD

    fnbase="house_s2_d1_ep${i}" ;

Thanks everyone for your help and suggestions (and patience),

[1] Season 1 of my source material was interlaced, season 2 is not.
    All this frustration and I didn't do a sanity check on the
    source material (any and all verbal abuse is warranted at this
    point)!
