Disc Scanning & Metadata Extraction

• Drive Identification

  • Launches MakeMKV in “robot” mode to probe the inserted disc.

  • Parses DRV: lines to map the MakeMKV disc ID to the actual Windows drive letter.

• Title Info Collection

  • Reads every TINFO:…9,0 line to capture title durations.

  • Reads every TINFO:…10,0 line to capture size estimates.

  • Reads TINFO:…2,0 lines for disc comments (angles, bonus markers).

  • Reads TINFO:…26,0 lines for segment maps (play order codes).

• Disc Type Detection

  • Determines “Blu-ray vs. DVD” based on total size thresholds and CINFO flags.

Title Filtering & Grouping

• Valid Episode Candidates

  • Filters out very short (< 10 min) and very long (> 70 min) titles.

  • Builds a set of plausible episode titles.

• Size-Based Clustering

  • Groups valid titles by file-size similarity (±15%).

  • Scores each group on:

  • Count Match (did it find exactly the expected number of episodes?)

  • Sequential IDs (are the track numbers consecutive?)

  • Size Consistency (low variance within the group)

  • Duration Consistency (similar runtime)

  • Segment Simplicity (simple segment maps get higher marks)

• Automatic Selection

  • Chooses the highest-scoring group; falls back to largest titles if no good group found.

  • For movies, it auto selects the largest valid title.

Title Correction

• Title Selection

  • Presents a checklist of all found titles (with duration, size, segment & comment shown).

  • Pre-selects the automatically identified set.

  • User can add/remove to correct any incorrect selections.

• Extras (Bonus Content)

  • After episodes are locked in, the remaining titles appear in a second dialog.

  • User may optionally select any extras.

Ripping with Progress Monitoring

• Per-Title Monitor

  • For each title, kicks off MakeMKV’s mkv command to rip to a temp folder.

  • Launches a background task to watch the newest .mkv file’s size and timestamp.

  • Every half-second, computes:

    • Current rip percent (current size ÷ expected size)

    • Throughput (MB/s) over recent history

    • ETA

  • Reports those values into the GUI’s progress bar and label.

• Step-Based Progress

  • Separately reports overall “steps” (scan, rip each title, rename, eject) so you see macro progress.

File & Folder Organization

• Episode Sorting

  • By default: uses the simple segment map (numeric play order) to assign files to episode numbers.

  • Falls back to title-number order if segment maps are complex or missing.

• Renaming Convention

  • TV: ShowName S00xxE00.mkv

  • Movie: MovieTitle (Year).mkv

  • Extras: ShowName S00D00 - Extra 00.mkv or MovieTitle (Year) - Extra 00.mkv

Transcoding Integration

• HandBrake Presets

  • If transcode=true, each rip (main & extras) is queued to a separate transcoder (AutoRipperTranscoder.exe).

  • Regardless of handbrake preset selected, all audio and subtitle languages/tracks are passed through and framerate is set to Same as Source/Variable

• Queue Management

  • You can choose to queue files and transcode 1 at a time, or allow multiple files to transcode at once.

FileBot Support

• Organize-Only Mode

  • If Skip Filebot Renaming setting is checked, runs FileBot on just the main episodes (excludes Extras).

  • Renames with format “ShowName S00xxE00 - Episode Title.mkv”

• Manual Extras Handling

  • After FileBot finishes, the “Extras” folder is manually moved into the library (preserving its naming scheme).

• Direct-Move Mode

  • If Skip Filebot Renaming setting is unchecked or no FileBot path is set, simply moves files in place without external tools.

Disc Ejection

• Tries multiple methods (PowerShell COM, WMI, CMD) to eject the drive letter.

• Retries gracefully if mapping isn’t found.
