Here's an update on this for those interested in H264 and VDR.

I brought up the problems with Spatial Direct Mode and FFMPEG on their
mailing list and Loren has implemented it within the code. When tuning
to one of the affected channels I no longer get messages saying that
spatial direct is not implemented, but I still get extreme
artifacting, dropped frames and problems with xine: -

video_out: throwing away image with pts 1124374 because it's too old
(diff : 31864).
buffer usage: 1689,  0,  0,  0, 0x9639a0
buffer usage: 1689,  0,  1,  0, 0x9639a0
ffmpeg_video_dec: error decompressing frame

video_out: throwing away image with pts 1138960 because it's too old

Hopefully, we can continue the interest and get these issues fixed.
Reinhard, do you have any idea why this might be occuring? I can
upload some samples somewhere if required.

Thanks
