Serviio

I have just upgraded from 1.4 to 1.6.1. The upgrade was fine, all settings transferred to new version, library refresh finished and I can see everything working in Serviio web console. However, the TV doesn't see any content in the library. I'm able to select Serviio as a source device, but when I try to browse the Video category, it always shows error message "No movies in this device". The same for Music and Photos.
I've checked it with other DLNA client (an Android app called Bubble UPnP) and the browsing is quite slow but in the end it works and I can browse and play the content of my library.
I'd like to ask if somebody else has had the same problem and how to solve it.
I run Serviio on Synology NAS as a DS manager package, if it does matter. I've also tried to restart it few times.
Thanks in advance for any answers.

Is there anyone with Samsung C series TV who could confirm if 1.6.1 works for him or not? Maybe I should try to reinstall Serviio? But how come it works with another client?

I don't have a C series, just H and JU series. These both see my media with no issues.

I have no explanation as to why some devices see media and some don't. Make certain your update didn't change your selected profile for the TV. I don't know how much work it is to remove and reinstall Serviio on a NAS, but might be worth a try as well.

Thanks for your input. The profile is set OK, I'll try reinstalling.

I have C series and it works well

I've got a Samsung BD-C5500 that won't play any online content (using Groovy plugin) with 1.6.1. 1.6 works fine. With 1.6.1 it usually tells me the video is an unsupported format but sometimes tries to play and screen is nothing but artifacts. Just fell back to 1.6 and all is working again.

What is the stream url and the plugin you are using? One of them is causing the problem.
