Media Center

The Media Center is Nebulae's optical cinema gallery. It presents your disc collection as a visual grid and plays DVDs, Blu-rays, and ISOs with full interactive menu support — DVD navigation menus, Blu-ray title menus, and (where a JRE is available) BD-J Java-powered extras.

To access Media Center, click the Media button in the title bar.

Note

Media Mode must be enabled. If you chose to skip it during first launch, go to Settings → BitTorrent → Media Mode and enable it. The setting takes effect immediately.

What the gallery shows

The gallery lists all torrent releases it detects as disc-based media. Nebulae inspects each torrent's file structure and identifies:

  • DVD disc sets — VIDEO_TS folders or DVD ISO images.
  • Blu-ray disc sets — BDMV folders or Blu-ray ISO images.
  • Boxsets — multiple torrents treated as a single multi-disc release.
  • Multi-ISO torrents — a single torrent folder holding several ISO images (each appears as a separate playable disc pill).

Each release appears as a card with a poster thumbnail (when available), the release title, and disc pills for each disc in the set.

Playing a disc

Click any disc pill on a release card to launch playback. The embedded VLC engine opens the disc in Nebulae's own player window.

  • For DVD releases: the DVD navigation menu launches automatically (dvdnav).
  • For Blu-ray releases: the Blu-ray title menu launches (libbluray).
  • For BD-J (Java-based menus): requires a Java Runtime Environment. If a JRE is found, full animated menus are enabled. If no JRE is detected, standard playlist and title navigation still works cleanly.

Resume playback

Nebulae remembers the last-played disc per release group. If you close the player mid-film, the next time you click Play on that card, it offers to resume from where you left off.

Adding media

In the title bar (when the Media view is active), a visible Add Movie / Disc button appears. Click it to select either:

  • A release root folder (containing VIDEO_TS, BDMV, or ISO files), or
  • A single ISO image.

The release is added to the gallery immediately.

Audio & subtitle preferences

Click the Settings (gear icon) while in Media view. It opens the Media Preferences panel (a subset of settings specific to language and playback):

  • Audio language — preferred audio track language (ISO code, e.g. en, ja).
  • Subtitle language — preferred subtitle language. The player selects matching tracks automatically when the disc is launched.

Disc format support

The Media tab in Settings (Settings → Media) shows the live capability status of the embedded player:

Capability Status
DVD Menus (dvdnav) SUPPORTED / UNAVAILABLE (shown in green or grey)
Blu-ray Menus (libbluray) SUPPORTED / UNAVAILABLE
BD-J Java Menus ENABLED (if JAVA_HOME is detected) / LIMITED

External media

Nebulae also lists external disc sources (discs that are not part of a managed torrent). These appear in a separate section of the gallery and can be played the same way.
