What player is so braindamaged and standards non-compliant as to
choke on an *optional* part of the MPEG-2 specs? (B frames are
optional).
Are you sure that was the cause or was it pusing the bitrate too high
and generating streams out of spec on the peaks? As I recall the
stuttering was caused by -b 9000. That can work with commercial
pressed DVDs but some players have problems with RECORDABLE media
at high bitrates due to the lesser reflectivity of the media.

Yep, that's the old behaviour.
I have a hunch that any problems with -R 0 are due to other factors
and not the lack of B frames.
Hmmm - having said all that it might be that DPME (Dual Prime Motion
Estimation) might be a possible problem area - can't recall if that was
required or not. It is possible to have no B frames and not use
DPME (but no B frames are a requirement to use DPME - at least at
[EMAIL PROTECTED]). If anything I'd have expected an old portable (Audiovox)
to have a problem with no B frame based SVCD and it sailed right thru.
