Is anyone successfully using the CVS version of mpeg2enc to encode
23.976 fps progressive material with the 3:2 pulldown flag for
playback on a 29.97 fps NTSC tv?  If so, can you post your mpeg2enc
flags?

I'm having fits getting this to work post-1.6.1.  I've tried both
"mpeg2enc -I 0 -p -F 4" and "mpeg2enc -I 0 -p -F 1", in the latter
case mpeg2enc seems to just force -F 4 anyway.  I've done this for
both "yuvkineco -F 1" video (animation) and a commercial DVD, with
the following results:

1.6.1 and before:  Works great

CVS: Linear increase in loss of sync.  Video plays too slow, on
mplayer at least.  Forcing -fps 40 fixes it, not sure why.  
Same deal if I multiplex with tcmplex instead.

The actual pulldown code is just a few lines, and is identical between
the versions.  I've tried using bbinfo and bbvinfo to compare the two
(not that I lnow what most of the output means).  One difference is
that 1.6.1 sets progressive_sequence=0, while CVS sets it to 1.
Another is that top_field_first is inverted between the two.
I'll be glad to provide logs or samples to any interested parties.

Dan
