mpeg2dec is a bad citizen in Stridesville.

Take the following video:

http://lycos.dropcode.net/xgl/xgl-gentoo-lycos.mpeg

which has dimensions of 764x556 pixels, so it gets cropped + copied befor=
e
sending it out, albeit the new I420 output buffer is allocated with wrong=
 size,
and strides (as implicit by X) are not taken into account when copying.

This is with up-to-date CVS, ie. including the fix from bug #330844 (whic=
h is
required).
