Good evening

Recently purchased a new Sony 65" 4k TV, and i have added the Sony UBP-X800 ultra HD 4k blu ray player.

I have purchased 4 x 4k  Ultra HD blu ray movies

I have played/watched with no problems 2 out of the 4.

Both Planet earth 2 & (spiderman home coming "this came free with the player') played ..with no problems.

I also purched The martian 4k ultra HD & Close encounters 4k Ultra HD

Had problems playing both these movies.

The Martian, stuttered for about 5min in the middle of the film, but then came good.

On Close encounters, about 1hr into the movie, it just stopped dead )frozen.

This resulted in the blu ray player freezing then restarting on its own.

Having  googled  this problem/issue, it would appear this player seems to have this problem quite a bit.

Has anyone had the same issues that could offer any help ?

It has been updated to the latest software, and i  selected the default settings when setting up, as this seems the most apropriate, The new 4k HDMI cable is also set to enhanced to allow the 4k.

I didnt expect to have these issues with the cost of this player.

I have only had it less than a week (purchased from John Lewis)

Could this be a fault, and should i be looking at returning, or is this something sony is aware of which will be fixed with a firmware update ?

Best Regards

Tom
