despite that spatial thing and interlaced support have been added for H264 decoding, I still have trouble with some movies, in which rainbow frames or something like that occur from time to time. these are mainly remuxes from HD DVDs or blu-rays to .mkv and those problems occur (at least in this case here, will have to check up on the others a later time again) not only with ffdshow, but also with coreavc and vlc.
I dont know whether this problem is still caused by something which is unsupported yet or if the remuxing process of mkvmerge causes these problems. I uploaded a sample of this remux, I tried to cut a sample from the original .m2ts file, but apparently I always hit an open GOP or something like that and when I muxed it it looked worse than now, with green stuff in it and such.
would be nice if someone could have a look at that, thanks!
