The attached patch against xine-lib-cvs/src/libmpeg2 fixes the above 
mentioned issues (and contains the vdr-xine changes, too).

decode.c contains two fprintf() debug statements: one reports the 
detected AFD value and whether it was detected at [S]equence, [G]roup or 
[P]icture level. The other statement reports AFD changes.

Be aware that AFD changes are detected in decoding order of the 
pictures. Further changes would be necessary to have them reported in 
display order (see comment in decode.c).

Bye.
