Built on Consensus
Every score aggregates ratings from multiple independent technical reviewers, not a single opinion. Different scoring scales (stars, letter grades, percentages) are normalised to a single 0–10 number so you can compare any disc at a glance.
How Confident Are We?
Every disc carries a confidence score from 0–100 reflecting how many reviewers have covered it. A disc scored by 4–6 sources carries a much stronger verdict than one with 2. We show this transparently rather than hiding low-coverage entries.
Picture Quality, Not Plot
We don't care how good the movie is, only how good the disc looks. Every entry is evaluated purely on transfer quality and HDR presentation. A great film on a poor disc won't make the cut.
What's In and What Isn't
Coverage spans discs actively reviewed by the community from January 2026, plus a curated selection of significant older releases added based on community popularity and transfer quality relevance. Film age is irrelevant, a 1969 restoration is as eligible as a 2025 release. A disc requires Blu-ray.com plus at least one independent source before it is published. Titles below the scoring threshold are tracked internally but do not appear in the public database.
Scoring methodology
Source tiers
Scores are drawn from six trusted technical review sources: Blu-ray.com, High-Def Digest, DoBlu.com, The Digital Bits, Blu-Ray Authority, AVSForum. A disc requires Blu-ray.com plus at least one independent source before it is published.
Score normalisation
Every source uses a different scale. We convert all ratings to a 0–10 baseline: stars ×2, letter grades mapped (A+=9.5 down to C+=6.5), percentages ÷10. Scores are then averaged across all available sources. A +0.2 DI bonus is applied when the 4K master is independently confirmed as native resolution. Scores are updated when new reviews are published — the detail panel shows the update date and reason when this occurs.
Classification thresholds
Reference ≥ 9.5 Gold standard. Demo-worthy transfers the enthusiast community regards as the best the format offers.
Excellent ≥ 9.0 Exceptional transfer. Buy with full confidence.
Recommended ≥ 8.0 Good transfer, worth owning. No meaningful reservations.
Notable ≥ 7.0 Competent transfer. Hidden by default, accessible via filter.
Below Threshold Does not publish. Tracked internally only.
Classifications are score-only. Confidence is shown separately and never gates the tier label.
Consensus & confidence
Consensus measures reviewer agreement via standard deviation of normalised scores: Strong Consensus (SD ≤ 0.5, 4+ sources) → Consensus → Soft Consensus → Disputed → Contested (SD > 1.5). Confidence measures coverage: how many of the possible sources have reviewed the disc. Both are shown independently because a high-confidence disputed score tells a different story than a provisional consensus one.
Streaming comparison
When a disc has a matching IMDb ID in the streaming database, a Streaming Comparison panel appears in the expanded detail view. Data is sourced from two tables: movie_streams (per-service HDR format, audio format, bitrate and peak nits) and a fallback to the main movies table (Dolby Vision, Atmos, HDR10+, bitrate, MaxCLL and MaxFALL) when per-service data is not yet available. Fallback entries are marked "basic data" in the section label.
Streaming verdicts
Each streaming service is assigned a verdict based on the following hierarchy, evaluated in order:
Suspected HDR Title is flagged as suspected tone-mapped HDR in the streaming database. Treat with caution regardless of other format claims.
Strong stream Dolby Vision + Atmos confirmed, bitrate ≥ 15 Mbps. Best available streaming presentation.
Good stream Dolby Vision + Atmos confirmed. Solid streaming presentation, bitrate below 15 Mbps threshold.
DV · No Atmos Dolby Vision present but Atmos not confirmed on this service.
HDR10+ only HDR10+ with Atmos but no Dolby Vision on this service.
Missing DV HDR10 with Atmos but no Dolby Vision. Disc DV grade not replicated on this service.
SDR only No HDR format detected. Significantly below disc quality on any HDR-capable display.
Limited quality Partial data available. Verdict may be updated as coverage improves.
Streaming verdicts reflect format availability only, not encode quality. A service may carry Dolby Vision but still apply heavy compression — bitrate and peak nits are shown where available to give a fuller picture.
