Broken VFR decode

(I'm not sure this is the right forum for this post)

1. How do I decode VFR correctly?
2. How do I get the frame number accurately?

I ripped a DVD and encoded with x264 in Matroska container. The rip has variable frame rate (60fps -> 30fps) in some small segments. The trouble is decoding the thing. The 30fps portions look choppy (like 3fps). EDIT:30fps actually looks like 60fps-pause-60fps-pause. Frame-by-frame looks OK.

I've tried decoding with ffdshow and the internal MPC decoders.

Also decoding the MKV file is strange. In AviSynth, if I use DirectShowSource I get 305781 frames, with DSS2 I get 306086 frames. So I'm not sure the ranges in the timecodes file are set correctly.
