I hope h_h's new 5.1 will be included. The MKV will be a BD compliant stream, so theoretically, if you used TS Muxer, you could split it into two AVCHD DVD9s.
This is likely to cause artifacts at cuttings points. The only tool that I haven't had such a problem with is Smart Cutter. However, I only use it for DVB streams, not Bluray.
As discussed per PM rendering the AVI in several parts is possible as we're using Avisynth input.
