Uwe Girlich's Demo Specs page has an updated version 1.1.2 of the recording FAQ and a new version of the MUlti-Level DEmo Repair kit (MULDER), which can now remove download sections in DM2 demo files and strips commands that disturb demo playback.

Some comments on the DM3 support in LMPC: I'm working on it (Who really didn't expected it?) but the source code and the resulting binaries are not included into the distributed packages (legal reasons).
