xbox one not able to stream video off of my Windows based pc!?

Different ways. You can use the Media Player app to stream OR use it to play media off a USB. You seem to want the Xbox One not to have this ability, even though it does exist.

From what the OP posted he is trying to play videos through Xbox Video, which is a service from Microsoft much like Netflix.

It's past midnight here but tomorrow if you don't believe me I'll record a video of me using the Media Player app to 'pull' media from my PC.

However in the meantime, would you believe Major Nelson and Albert Penello https://www.youtube.com/watch?v=qe28yty02SI.

That is exactly what I've said Farscape, top show by the way.

Either I've been explaining myself far more badly than I'd thought or eber3 doesn't want his impression of the One not being able to 'pull' media challenged.

the media player includes dlna, so streaming from a pc, network drive works perfectly for me, you have the option to play files from usb also.

Maybe I'm reading something wrong at your link, but I see this...

"What are the different ways to play audio, photo and video content on Media Player?"

ANSWER: "You can play media from a USB 1.0, 2.0 or 3.0 removable drive."

So no mention of streaming directly from your PC.

"Is there third-party software that I can use to stream media content from my PC to Media Player?"

ANSWER: "The Xbox One team tests extensively to ensure that Xbox will work well with Windows Media Player software. If you decide to use third-party software, contact that software’s manufacturer for support."

Why would you need a third party to stream content if Media Player had that ability? Looks to me like X1 can only play content via USB or other removable device unless a non supported third party work around is used to stream content to Media Player. Big
step back from the 360. Don't know why they just didn't make it work with "Media Center" like on the 360.

The Xbox One can do that without using Play To.

Either search the app store for the Media Player app or plug in a USB with media files on it to be prompted to download it.

Once downloaded it can 'pull' video from your Windows based PC. Never tried viewing pics with my One though.
