MultiAVCHD and AVCHDCoder both just don't work with x264 64bit - Why?

[borst_one]

Hey guys,
I already posted in two other threads here in the forum. I'm trying to transcode holiday videos for a friend. Whilst I was very happy to find tools like MultiAVCHD and AVCHDCoder which offered all the options and settings I needed (joining of mts files, reencoding as strict AVCHD compliant dvd-9) both tools only transcode with the 32bit version of x264. That leads to a cpu usage of just 30% on my AMD PhenomII sixcore. A forum user recommended I should try RipBot. That tool works fine with the 64bit version of x264 and due to that, I'm able to encode the video media with roundabout 32 fps in contrast to 10 fps with AVCHDCoder or just 1.4 (! - yes 1.4) frames with MultiAVCHD.

Both tools offer me the option to active 64bit encoding in the settings but both tools don't work after activating it. MultiAVCHD just says transcoding failed

and ACHDCoder just uses the 32bit version instead of the x64 version. I even tried to overwrite the 32bit versions with the 64bit versions. That solution led to non encoding at all in both tools.

I would be so grateful for an explanation or help!!
