Identify which scheduling model is active
NextPVR's Recording Schedule documentation describes manual recording fields and advanced conditional rules. It specifically notes that start and end times are ignored when advanced rules are set. A form containing both does not establish that both constraints will govern the result.
State the requirement before editing
For a permitted time-window capture, record channel, date, start and end. For a content-based rule, record the intended matching condition and its scope. Decide which task you need rather than filling every field as a precaution.
Preserve the old definition and inspect generated pending recordings after the change. Include an event outside the intended window or a near-match title in the review as appropriate. This makes a scope mistake visible before relying on the recording result.
Keep the rule understandable
Avoid copying an advanced condition you cannot explain. Use the installed documentation and a small sample before expanding it. No schedule or conditional query was executed for this article, and the presence of times in a dialog is not proof that they restrict an advanced rule.
Questions answered
Do manual start and end times always constrain an advanced rule?
The checked schedule guide says they are ignored when advanced rules are set.
Should I fill every field to make the schedule safer?
First choose the scheduling model and verify its generated occurrences.
