Problems streaming to Rokus

[ftanner]

I've switched the device drivers to Roku (mkv) and that helps. However, I'd like to try to choose formats to pre-transcode for the Rokus. Problem is that no formats are highlighted when I try to choose formats for transcoding, meaning Mezzmo doesn't consider any of my files to be necessary for transcoding. Despite that, Mezzmo transcodes the movie on the fly and this is what causes things like inability to FF. I sure would appreciate some guidance on what to pre-transcode for Rokus. AND I'd like to understand why movies are being transcoded even when the native format is supposedly supported by the Mezzmo app on Rokus.

I have mine set to Roku 4k, since my devices are the Ultras. I'm not sure what difference that makes.

The Roku 4k profile has a max resolution of 4k and support for h265 codec.

Tried it. Didn't work. And these aren't 4k files.
