Initial Comment:
I have been using libdv to decode dv pal dv frams with
a resolution of 720 x 576. I built libdv with the above
option. However when using dv_decode_full_frame in the
yuv colour space, the pitches pointer seems to get a
little trashed. In the function 
void 
dv_mb420_YV12_mmx(dv_macroblock_t *mb, uint8_t
**pixels, uint16_t *pitches,
                  int clamp_luma, int clamp_chroma) in
YV12.c, the value for the pitches[1] is also zero when
set from elsewhere. I am assuming that this is being
trashed somewhere.
