I used MeGUI to get the audio track from the PAL GOUT in sync with Harmys DEED 1.0 version. There is a function to convert the audio track from 25 fps to 23,976 and the audio tracks matched with the video on all three movies after the remux.

MeGUI might be the most powerful tool to make x264 encodings but sadly I must say that I have no idea how to tweak the settings to get the best results.

When I encode a video with MeGUI I simply choose the x264:AVCHD 5/9 2-pass mode for a DVD-R and the movies play fine on my standalone. But there are probably many things that can be tweaked...
