It appears it is the "format profile" level that is the issue. Anything 4.0 or higher will not play on my Samsung 7000 TV. I can check the programs and if they are at the higher level I can convert them to mp4's using ffmpeg myself. However, I would still like to know how to "force" UMS to transcode these files and make them the default stream.

Could be but looks like both files are at level 3.1, and both are using the h264 codec. I did notice that the first one is using aac for audio while the second uses ac3 though, that might be the reason why but without knowing what formats it supports its just a guess.

I did find this https://wiki.samygo.tv/index.php?title= ... y_and_DLNA which seems to be everything that can play on a Samsung tv and it does look like aac is not supported in mkv files.

I used that to redo the Samsung-CD-conf and hopefully it will be more accurate now. If it works better I'm sure it can be updated in the UMS installer.

Good to see that UMS is detecting the right TV now, but looks like my last config didn't work as I guessed that it might just match the model number. :(

In theory adding MKV (or even * for all) to the force transcoding in the transcoding settings should do it, but you may lose the ability to FF and RW. My Samsung TV does that for transcoded files as it has no way of knowing the length of the file. The ideal situation is only to transcode when the video is unsupported.

Try and get some more trace logs with that new config so we can see if it makes any difference.

The new conf file did not change anything. You are right, it is not the format level. I did more testing and you could be right that it is the audio codec. I attached the trace files for the failure and 3 more mediainfo files. 7x01 works. 7x02 and 7x03 fail.

Yes it definitely looks like its the audio codec that is causing them to fail.

Looks like you renamed the original "Samsung-CD.conf" to "Samsung-CD - Copy.conf" before copying over the updated one. unfortunately your UMS is using the copy to match to your TV so it ignores the updated one, since they use the same UserAgentSearch string whatever comes first takes precedent. try moving the original file to a different directory, or rename it to "Samsung-CD.conf.bak" give that a go and post updated logs.

I noticed you have a H series too, how well does it work with UMS?
