Not really, there is still some other issue.
Try
./ffmpeg_g -y -flags +bitexact -dct fastint -idct simple -sws_flags +accurate_rnd+bitexact -t 1 -qscale 10 -f image2 -vcodec pgmyuv -i ./tests/vsynth1/%02d.pgm -f s16le -i ./tests/asynth1.sw -ar 48000 -bf 2 -timecode_frame_start 264363 ././tests/data/b-libav.mxf -debug 4

On x86_64:
[mxf @ 0x2bcf680]frame 264363 2:56:14:13

On PPC64/Altivec:
[mxf @ 0x100795d0]frame 872448 9:41:37:23

It seems to be mpeg12enc.c that writes different values into the
MPEG2-file, but I have no idea why nor why the MPEG2 regression tests do
not catch it...

Btw. your mxf_parse_mpeg2_frame could probably make good use of the
mpegvideo.h header, in particular ff_find_start_code, EXT_START_CODE,
GOP_START_CODE, SEQ_START_CODE and PICTURE_START_CODE.
