If you don't want to wait for the official Bluray to be released or don't need lossless audio and menus, you can as well get the mkv version right away and simply create a BD out of it using TsMuxer.

Sounds good, but I didn't get it to work... when I put the MKV in tsMuxeR GUI to create a "Blu-ray disk" (per selection), I get an error code -2 "Matroska parse error: Invalid EBML number size 2 at pos 273027604"... any help?

It happens right at 1.4% progress, after the audio tracks are "decoded" as per the output window, and right when it says "B-pyramid level 1 detected. Shift DTS to 2 frames"

I've already muxed the corrected German and Spanish audio tracks into the MKV... could that be the cause?

Edit: Got it working now... Looks like ffdshow was the problem. I set its h.264 decoder to "deactivated" and now tsMuxeR seems to work. Veeeery slooowly though... I would've thought, since the video doesn't need to be re-transcoded, this would be relatively fast. But judging by the current percentage, this'll take over an hour.
