Summary0012727: MMW prevents Power Options when Video is paused
DescriptionWhen playing Video files MMW adjust/prevent laptops to go to sleep.

This should not happen if Video is Paused and when Low battery warning event is received.

Strangely I could not replicate on Desktop PC Most likely as UPS uses its own app to control PC and when that app is disabled I get no readings on UPS state.

I tested this today on friends laptop and user is right.
When Video is playing it goes playing even Windows announces LOW battery and wants to do stand by/hibernate.
MMW prevents that and drain battery completely.
I tested this also on MPC (MediaPlayerClassic), POT/DAUM player, WMP and when Power control send Low battery Event to hibernate than apps comply, while MMW ignores it and return Event Handled leading to battery drain.

MMW should Only prevent Screen OFF and standby while playing and not system Hibernate event from Power options.

Peke, are you sure that video playback of _local_ files causes this?

From what I see in our code, we prevents computer from sleep only when burning CD/DVD/BD, syncing a device or streaming via UPnP/DLNA (i.e. when a video is being streamed from MM server).

Are you sure that you and the user haven't tested playback of files streamed from MM server? If it happens during playing of local video files then it could be caused rather by a specific video codec that MM uses.

Could you please write down exact steps to reproduce and get debug log?
