Keep source transitions and symptoms separate
A programme can move between production segments, inserted material or other source states. The relevant packaging must describe transitions correctly for the player. A viewer's useful observation is what happened at the boundary, not an assumption that every marker is an error.
Record whether picture, sound, time display or the application itself changes. A short transition, persistent loss of synchronization and complete playback failure are different outcomes. Preserve the exact programme and approximate position.
Compare a reproducible point
For a permitted recording, note whether the same position fails again through the ordinary playback controls. Avoid repeatedly scrubbing rapidly around the boundary, which adds another workload and session pattern. One clean repeat and one comparison item can establish useful scope.
An illustrative recording that fails at the same transition on two verified local paths warrants a source/player-boundary question. That does not prove the media is incorrectly packaged; the operator or developer needs to inspect the actual resource and client behaviour.
Keep continuous playback and a direct seek as separate comparisons. A client can initialize differently when opened near the boundary, so a successful seek does not automatically reproduce the earlier transition.
Do not repair packaging by editing a private playlist
Removing a discontinuity marker can hide information the client needs. Adding one by guesswork can create another mismatch. A customer should use the current authorized resource and report the boundary rather than rewriting media instructions.
If a developer requests diagnostics, provide the relevant safe excerpt and player version through an appropriate process. Full playlists can contain active media addresses, and logs can include credentials. Preserve the useful marker context without publishing the source wholesale.
Retest the original transition
After an authorized source or player correction, play across the same point under ordinary conditions. Record whether the original symptom changes and whether another part remains affected. A successful start from the middle is not necessarily the same test as continuous playback across the boundary.
A discontinuity explanation does not establish programme rights, recording permission or a universal player-compatibility claim. It identifies a technical place where the source timeline and client handling need to agree, with the actual viewing result kept central.

Does a discontinuity marker mean the internet disconnected?
No. It is media-playlist information. A network-disconnection claim needs separate evidence.
