That video is being transcoded as the width is too large for the TV

Because of this it has to be scaled ...

Something about those videos or the conf file for your TV is causing UMS to transcode those videos as it thinks they are unsupported.

To be able to see why I will need to see logs. See the section in red above.

I see it is failing as 'libx264' is an unknown encoder.
The reason for this is the wrong version of FFmpeg was used in the Linux release for 14.12.0 where that option was not enabled when it was compiled.

This was reported here and fixed in 14.12.1
There is a test build still available there with ...

I checked the logs and can see that UMS has to transcode that video for the TV to be able to play it.

If you forgot the login details you set you can delete "C:\ProgramData\UMS\database\USERS.mv.db" to reset it and it will ask you to crate a ...

If your computer is connected to a wireless network then it will use that.
If you have both wired and wireless connected then this is when you might need to force one or the other.

The important thing is to make sure the computer and your devices are on the same subnet for them to be discovered ...

Those warnings can be ignored. There was a change to another networking library that logs much more than the old one.
These will not be logged in the next release.

Those are coming from 192.168.178.8 so it may be related to the thumbnail problem as this is the TV they do not show on, otherwise it ...
