Decimate Gurus I need your help

i have an interesting 59.94 progressive HDTV stream


the problem is there is no static pattern for dupe frames.
Normally i would use selecteven() or selectodd() to get down
to 29.97 then a Decimate(5) to get to 23.976 and all would be
good to go. But this stream is wacko. There is a single
frame randomly placed in it every 10 to 40 frames with NO dupe
frame. Now what is more wacko still is this single frame does
not happen the whole way through. minutes can go by with no
single non duped frame then all of the sudden they start up
again.

if i use selecteven() or selectodd() then 50% of these are cut
and i get a jump which of course looks bad.

if i use decimate (2) then the 2 frames will NEVER be dupes
since the one is always the only one so 50% of the time it
gets deleted there too since it is randomly placed.

the basic pattern normally is AAABBCCCDD the whole way but
this stream is

AAABCC or AAABCCC or AABCCC (it randomly changes as it goes)



suggestions?
