Do you use hardware acceleration on PC with GF9400?

so is hardware acceleration supported with 9400gt?
noting that it works perfect with any avi ,mp4 or mkv except those formats i mentioned
it worked fine when i disabled it with those formats ,but here is what i suppose to be a bug needing to be fixed
when disabling it detail boost and other features would be still in effect ,until i press o 'the options" ,it would then disable these options and its effects
by the way motion2 with these files make it streaking ,it's the only effect i got
i wonder why the detail and light boost features are disabled when unchecking hardware vizualization though ,as i said it is working fine when unchecking hardware acceleration until i press o
i hope you make up your mind for dvds

PLease try the following:

Stop a playback. Disable hw acceleration in settings.
Open playback options. Enable "best quality" option.

This should solve a problem with not working playback options.
