Some Blu-Ray rips arrive as BDMV folder structures rather than .mkv files. Radarr can’t import these — it only handles single-file containers. MakeMKV converts BDMV folders to .mkv files that Radarr can ingest.

Workflow:

1. BDMV folder lands in /mnt/seedbox/movies/ (e.g. BLENDED/, Inherit.the.Wind.1960.MULTi.COMPLETE.BLURAY-OLDHAM/)
2. Open MakeMKV web UI: File → Open Files → navigate to /storage/
3. Select the main feature title (usually the longest)
4. Output to /output/
5. Move resulting .mkv into /mnt/seedbox/movies/ for Radarr import

The jlesage/makemkv image defaults MAKEMKV_KEY=BETA, which on container start tries to fetch a fresh beta key from forum.makemkv.com. This fetch hangs indefinitely over the WireGuard tunnel (CT100’s outbound goes through UltraCC NL), and the container never finishes initializing.

Fix: explicitly set MAKEMKV_KEY: "" in compose. Empty string skips the key-fetch logic entirely and the container boots normally. The 30-day eval license is fine for occasional use.
