The problem i'm having is that the videos that i encode using the latest x264 these days plays mostly fine with the ffdshow ffmpeg-mt codec but if i enable the ffdshow DXVA plaugin the same videos tend to just display a single frame.
are the latest x264 really so ahead that that the DXVA filters are not up to them.?

You need to use DXVA-compatible encoding settings. DXVA has limitations (depending on your graphics card).
Btw, it could also be the ffdshow has a bug. I always test w/ the built-in Microsoft H.264 DXVA Decoder that comes w/ Windows 7.

Seems like either its a bug in ffdshow DXVA filter or its outdated enough to not support the newer features.
I had the same problem with coreavc before.
The video seems to be playing fine using the mpc-hc builtin DXVA decoder.
Just for reference here are the settings i used.
program --preset fast --tune animation --pass 2 --bitrate 1500 --stats ".stats" --open-gop normal --bframes 16 --b-adapt 2 --ref 16 --weightp 2 --qpmin 10 --ratetol 5.5 --rc-lookahead 55 --aq-mode 2 --merange 32 --me umh --direct auto --subme 8 --partitions all --trellis 2 --no-fast-pskip --output "output" "input"
