PlayTo not working because of XML encoding error

[siddhartha 11]

Using Version 3.1.6153.29987 dev

 

What is happening is that parsing the JSON DLNA profile into XML is throwing HTML character encoding errors on:

 

"XmlRootAttributes":[{"Name":"xmlns:sec","Value":"http://www.sec.co.kr/"}]

 

It doesn't like the colon in xmlns:sec. This breaks many DLNA profiles.

I'm getting a similar XML error after upgrading to the latest beta 3.1.210.0 to my LG55LB6100. It was working perfectly prior to today's update. The LG sees Emby just fine, but when I hit it I get the No Files error on the TV and no folders show. I've rebooted the PC and the TV.

Awesome, thanks for the report. Let me know if the next build resolves it.

Hooray!!

 

Searched the forum before reporting this same behaviour (unable to play to my new TV (LG 65UH770) everything fine up until hitting 'Play' (on iPad cleint) then nothing.  I hadn't tried for a couple of days so read the thread and tried again, and hey presto all is well.

 

Thanks community and team!!
