@Gregtr Having just read your post I tried adding Last of the Summer Wine from Drama/Gold to my playlist and it worked with no problem so the streaming rights appear to be in order.
Have you tried a reboot of your Glass TV. Simply unplug it for a minute or two and then plug it back in again. It will take about a minute to reboot and just like most electronic devices it will often resolve minor software glitches.
Good luck 🤞
