Blu Ray app changes the TV resolution and does not play dvds

Yes, I tried this twice. I even unplugged the console and TV then deleted and reloaded the app. No change. The App always tries to switch the TV to 1080p even though it does not support that resolution. It only started doing this after the last update.
The strange thing is that it only does this with DVDs not Blu-rays. Blu-rays play at the standard 720p

So I tried this today. Went to Settings>Display & Sound>Video Output. Went to Advanced video settings and selected HDMI instead of Auto-detect. Then I selected 720p for TV resolution. Saved. Turned off the console (and unplugged it) deleted the Blu-ray App
and reinstalled. Played a DVD - No change! It still attempts to switch the TV to 1080p distorting the picture. There is one change though - now it switches to 1080p for some Blu-ray Discs as well. So things have gotten a little worse. Luckily I can still
bring back the TV picture by quitting the Blu-ray app. Games and streaming videos are not affected.

I cleared the Persistant Storage and power cycled (and unplugged) the console three times in a row. No change. DVDs are still playing at 1080p instead of 720p. Blu-rays are OK at 720p. I did this whole procedure twice, just to be sure. I wanted to make
sure the TV wasn't the problem, so I unplugged the HDMI cable from the rear of the Xbox One and plugged it into an Xbox 360 S that was set to 720p on HDMI. I played the same DVD on the 360 and it played perfectly on the TV with the same input. The Blu-ray
app just seems to be over riding what ever the system resolution is set to and tries to play DVDs at 1080p.

Hi there,

The Xbox should be upscaling video resolution to what is capable by the DVD and the TV. Whenever you play normal HD DVD's and the resolution is displayed by your TV in 576p, what is the resolution displaying in your Xbox video settings? Take a look if the
resolution setting is still at 4K or 1080p whichever you have it set to when you play your DVDs.

Have you already tried re-installing the Blu-ray player app? If you haven't, I suggest doing so and let us know if the problem persists.

Optical drives can't change resolutions, that's not how they work. Only the Blu-ray Player app could do that. It won't because to do so would be to make the picture worse.

Unlike OLD CRT TV's (you know, the big TV's back before modern flat screen LCD TV's were the norm.), modern TV's don't look great running in lower resolutions than their native resolution. Try playing an old, now Retro, console like a Super NES on a 4K TV as apposed to an old CRT, and you'll see what I mean.

If you set the console to 480P on a 4K TV it's going to look soft and blurred and this will translate to a soft and blurred picture when watching a 480i DVD on the Xbox. Modern TV's have upscaling tech too, but there are limitations.

Bear in mind that some films on DVD and even Blu-ray were poorly mastered to begin with. If they're already poor quality, reducing the resolution on a modern TV will likely just make them look worse.
