Hello,

what happens if you add "-fps 30000/1001" to both passes?

You should also leave the bitrate (rather: all lavc-options) the same on both 
passes! 
Only exception: If you want the first pass to be fast, you can use the 
"turbo"-option on it. This will deactivate cpu-intensive options, without 
screwing 2pass up.

Another thing, that comes into my mind: I had some trouble using pullup with 
mencoder a while ago. Using filmdint instead did help back then. Maybe you 
should try.
