Thanks for the reassurance, Mike.  You are correct that the -vf pullup seems
to display the video correctly.  This is good news.  But is there a way to
issue the following parms (-vf pullup -ofps 24000/1001) without re-encoding,
i.e., perform *only* the ivtc with no loss?

Obviously, I have no idea how to use this tool at all, because my first
instinct was to try this:

mencoder -vf pullup -ofps 24000/1001 24p000.m2t -oac copy -ovc copy -o
output.m2t

which produces a horrible output with artificats everywhere :-)  What else
can I try?

Thanks,
Chris
