MKVs with DTS or AC3 to Blu-ray legal file

[mmace]

Hi guys, been making Blu-rays for about a year now, I own DVDit Pro HD (don't use this anymore as it was useless!), Encore CS3 (rarely use, only use for complicated discs I make) & Nero with HD-DVD/Blu-ray plug in.

I have loads of HD films in MKV (720p and 1080p x264 with a mix of AC3 and DTS audio) container as well as a few MPEG2 (.mpg) with AC3 or DTS.

I mainly use Nero these days due to ease of use and speed to put a project together. I usually have a first play video followed by a custom menu and then a couple of films (most are small enough to have 2 on 1 25Gb disc). The problem I'm having is getting the MKVs into a format that Nero likes without having to re-encode.
I can easily convert x264 MKVs to MPEG and convert the audio to AC3 all in a mpg container, but when I load it into Nero it won't use smart encoding on the video and re-encodes it.

Can anyone suggest a way to transcode or remux an x264 MKV with AC3 or DTS (i have both types) to something Blu-ray legal without it being encoded twice and taking 1.5 days to do so?

thanks in advance for any help

TSmuxer if the mkv is legal to start with ie not cropped and has less the 4 frames per reference if its 1080p. it must be 1280x720 or 1920x1080, if not you have to reencode to add borders which on a fast machine takes about 3 hours then use TSmuxer to create BD structure.
