You might in fact need ugly or bad plugins, MPEG2 is among them afair.
That would be unfortunate, those plugins are not foreign-arch-installable in Debian. I will try running wine inside the i386 chroot I used to build it.
Of course, wine should not crash just because gstreamer does not support the given media, but that's another bug (if it is the reason for my troubles).
