Thanks guys for the quick reply!
I tried the DirecTV profile - didn't work.
To further clarify: the tablet's DLNA player does see and connect to Serviio; it can even see folders, videos, titles and the thumbnails that Serviio provides. It just can't play back the content. Error msg is "The device can't play this content."
Regarding the throwing of videos to the TV, The TV has been automatically added to the Tablet's DLNA controller as a renderer device that can be thrown to. The problem with the DLNA app is, you can't throw media to another device until it has started streaming to the tablet first. A button appears for throwing the content to another device only after the stream has successfully started playing on the tablet. The source content does not have to reside on the tablet to be thrown to the TV (I'm sure you already know that though). I'm assuming the Media Server is supposed to know it now has to transcode the file for another device when it has been given a "throw" command from the tablet's DLNA controller. I'm assuming the Media Server has to have transcoding profiles for both devices to support this kind of throw action. Let me know if I'm understanding it correctly. Also, as I mentioned before, I have been able to successfully throw MP3 audio streamed to the tablet from Serviio to the TV without a hitch.
Finally, Device Spy doesn't show the tablet, unfortunately. I have included the link to the DLNA certification here:
