Encoding to PAL DV25 (yuv420p) with v0.7 rc2 produces corrupt output

[GoogleCodeExporter]

The source here happens to be IMX30, but the issue can be seen on my default SD 
DV test clock clip.

Command line here:

ffmbc -v 9 -loglevel debug -threads 1 -i primary-2011-10_05_1039-34.mov 
-vframes 250 -vf crop=720:576:0:32 -vcodec dvvideo -pix_fmt yuv420p -r 25 
-aspect 16:9 -bff -acodec pcm_s16le -ac 2 -ar 48000 -f mov -y out.mov

Corruption can be seen where it is obvious that interlaced DCT macroblocks 
would be being encoded.

If the source material is progressive (even if it's flagged as interlaced) then 
there is no corruption.

For instance: compare a frame from the original PAL IMX30;

With the encoded frame from the PAL DV25
