Starting Video half way through.

Hey all.

Running Plex on my Xbox One using the latest PMS. I have noticed over the last few days that when playing back a 49 min TV Show, it starts at approx 30mins.

This seems to only happen with XB1.

I haven't manage to test on Movies or a different show yet.

Anyone else having a similar issue? I have rebooted the XB1 a few times but it mainly stays in standby. Also it seems to happen even through I've just played back another video previously.

Thanks all :)
