Public bug reported:
Binary package hint: mpeg3-utils
AMD64 $ mpeg3cat DEAD_LIKE_ME_S1_D1_US/VIDEO_TS/VTS_01_1.VOB > foo64.mpeg
Segmentation fault
x86 $ mpeg3cat DEAD_LIKE_ME_S1_D1_US/VIDEO_TS/VTS_01_1.VOB > foo.mpeg
Hit end of data in DEAD_LIKE_ME_S1_D1_US/VIDEO_TS/VTS_01_1.VOB

The other tools aren't 64bit clean, either:

And FYI, the AMD64 architecture includes MMX, so it can be enabled
without runtime checks on amd64.
even on x86, mpeg3cat still segfaults on a file produced by mplayer -dumpstream
dvd://42:
x86 $ mpeg3cat -a0 s1.t42.dump > s1.t42.ac3
Segmentation fault
Although that file isn't empty, it isn't a proper ac3 file either.
mplayer says a52: CRC check failed! repeatedly.
