ATV screensaver resume freezes video

[titanous]

On Apple TV with the latest release version of MrMC when coming back from the Aerials screensaver, pressing play will start the audio but the video will not start, remaining on the frame that was paused. This happens ~90% of the time, I have not identified a common factor. A full stop+resume is required to get the video and audio to play at the same time when this happens.

Reproduction Steps

1. Enable the Aerials screensaver with a short idle time.
2. Open MrMC and play a video from Plex.
3. Pause the video.
4. Wait for the screensaver to start.
5. Press a button to exit the screensaver.
6. Press play.

Expected Result

The video and audio start and play in sync.

Actual Result

Around 90% of the time, the audio will play but the video will stay paused.
