Background

The Author, Rip and Blu-Ray modules depend on dvdauthor, spumux, and xorriso � all Linux-only tools with no Windows equivalents. As of dev32, all three modules are hidden on Windows until a cross-platform solution is available.

Blu-Ray module currently has zero functionality; only a placeholder button on the main menu (currently hidden on Windows)

Goal

Implement DVD/ISO/Blu-Ray authoring natively in Go so the Author, Rip and Blu-Ray modules work on all platforms without requiring WSL or third-party tool installs.

Scope

DVD VIDEO_TS structure generation (currently done by dvdauthor)
SPU/subtitle mux for menus (currently done by spumux)
ISO image creation from VIDEO_TS (currently done by xorriso/mkisofs)
ISO extraction for ripping (currently done by mount or xorriso)

Constraints

Must be lightweight � no 5-10GB WSL Ubuntu install
Pure Go or minimal CGO preferred to keep the binary self-contained
Should produce standards-compliant DVD-Video ISOs readable by players

Notes

FFmpeg handles MPEG-2 encoding and works on all platforms already
The ISO format (ISO 9660 + UDF) and VIDEO_TS layout are fully documented standards
Existing Go libraries to evaluate: none known yet � likely needs custom implementation
