FWIW, I was able to transcode a 1080i clip (or was that 1080mbaff? :)  
from HD-PVR just fine with this patch.

MPlayer with the patch was also improved, it was able to maintain A/V  
sync when playing with -demuxer lavf. It was unusable previously. It  
also played interlaced streams from DVB sources that have been  
troubling me.

I'll keep playing with it to see if anything broke.
