Why there is no support for MPEG2 in hardware in practice, theoretically I see it internal filters but when I reproduce a DVD the DXVA is not used, this has been going on for ever, when are you gonna fix this?

SOme MPEG4 video won't be accelerated with UVD2 or DXVA even when I configure FFDSHOW filter to skip all compatibility checks so it can accelerate all MGPE4 videos.

how about using both 64bit & 32bit just install 32bit & restart after that install 64bit,
Q: advance configs ?
A: depends on how 32bit worked on ur pc & how 64bit works.
i've just installed them adding all options to max
& thumbnail preview with poth 32bit & 64bit, WMP crashed a bit which happen while switching to another video but their was no serious errors besides it was pretty fast & for now it works on fine on mine, well its up to u to decide....id prefer it if the PC pro bro's out there could give me a heads-up :)

the same problem also occur on me where the generation of thumbnail cache will crash the windows explorer.. But the x64 is more faster than x86. so basically i love it.

sometime.. the x64 play RMVB file without audio .. so i wonder what happen?

I did instrall both 32bit and this one only for a reason to thumbnail video clips. it's quite strange that sometimes on windows 7 64bit systems, when trying to thumbnail RMVB files, the explorer crashes.

Also h264 packaged AVI files may not seems to be thumbnailed.
