I've noticed some problems with blu ray playback on my brand new Xbox One S.  When I put a disc in and the video starts playing, the image is corrupted in some way - it looks like it's split in thirds - and then the screen goes blank.  Sometimes the sound continues to play, sometimes not.  Controls don't seem to work and the only thing I can do is to hard reset the console.  At which point, the disc will then play fine.  I experimented a bit yesterday and found that the disc will play fine if I do a hard reset of the console before putting it in.  If I reset the console from within the dashboard it doesn't work, it has to be a hard reset every time.  

I made sure the console and all apps were up to date, so should be no issues there.  I quickly scanned Google for suggestions and found a forum which effectively suggested I do exactly what I'm already doing, but this doesn't sound good enough for a brand new and not-cheap product.  I don't think my expectations are too high for a new device to do what it claims to do without resorting to ham-fisted workarounds.

Is this a widespread problem, or is something else at play?  I did wonder if the HDMI cable was faulty, but I swapped it out and it made no difference.  It's connected to a Pioneer AV receiver, but other equipment plays fine so I don't think there's a problem there.  Which makes me think it's the Xbox, but short of taking it back and swapping it out, I can't think what else to try.
