It's not easy; but doable.
Here's how it goes :
1)Extract the streams from mkv and make them separate using MKV Extract.
2)Choose the streams you want.
3)Use H264info to make x264 streams AVCHD compatible (not re-encoding; it only changes flags and metadata on the stream). MPEG2 streams don't need any fixing and you barely find any VC1 streams. use 4.1 setting for the level
4)Use TsMuxer to mux the fixed x264track with the audio tracks you want (could be multiple audio tracks) and make a TS file
5)Now you can TSRemux to either make a BMDV folder and burn that folder by nero using UDF 2.5 setting
I watched many stuff (including HD TV shows) this way. You can also use Nero to play around with AVCHD files and add menus and such.
Doom9 is an amazing place. They help you as much as they can and you can find lots and lots of information over there.
