[Beta testers wanted] MediaCheck — read-only Windows media health and duplicate checker

[guy_incognito19 0]

I am looking for a few Windows users to test MediaCheck 0.15 Beta. It checks the media files themselves rather than connecting to an Emby database, so it can be used with an existing Emby library without changing Emby or the media files.

Current features include quick FFprobe checks, optional full video decoding, plain-language issue explanations, multiple library locations, cached refreshes, focused rechecks, scan history, and read-only duplicate comparison. It never renames, moves, repairs, or deletes media.

The package contains the installer, a 25–40 minute testing checklist, feedback form, privacy/support explanation, SmartScreen instructions, and checksums. I am particularly looking for feedback from users with large collections, multiple drives, NAS folders, or known problem files.

Download and details:
https://github.com/stewlowe/MediaCheck/releases/tag/v0.15.0-beta

Please reply in this thread with feedback. If a problem needs more detail, MediaCheck can export a privacy-conscious support bundle from its Diagnostics window.

The beta is free. The installer is not yet code-signed, and the application may eventually have a paid edition; both points are disclosed before download.

Development disclosure: the project was built with substantial AI coding assistance under my direction and has 73 automated tests plus hands-on Windows testing.
