A source is saved in MYTVOnline, but video will not play: separate the stages

Confirm the entry matches the account method

Formuler’s source guide distinguishes MAC-ID, XC and M3U. Verify that the chosen form matches the details supplied for that method. A saved name or portal address does not establish that registration or credentials were accepted.

Use the installed MYTVOnline generation’s menu. The correct route differs between versions 2, 3 and 4, so a screen that looks different from a tutorial may simply belong to another generation.

Describe what actually loaded

If no categories appear, retain the account/connection error. If categories appear but the guide is empty, note that the catalogue response worked and that guide data remains a separate question. If the guide works but video fails, capture the media-stage message.

This sequence prevents a broad reinstall from erasing useful evidence. Re-entering every value without noting the result makes it difficult to tell whether a source-format correction changed anything.

Test a small set of authorised tasks

Try one known item, return to the category list and inspect the audio/subtitle controls where available. Do not use a large library’s presence as a substitute for an actual playback test.

Keep any source/account conditions in view. A software menu can expose recording or catch-up options even when the account or source does not support the intended task.
