I'm tired of Hearthstone being recorded while in queue for a game of League. And also don't want other games I'm playing to be recorded (stardew valley, alien isolation, etc)
I remember seeing a thread made about a year ago that asked the same thing and was told by a staff member it was added to the feature request list yet it's still not an option for us to use.
What's the holdup?
Well actually, it has been added as a Feature :-)
You can go into the Plays.tv Preferences and under 'Advanced' you'll find "Manage Applications". It's there that you can find the exe names of which games you do not want to record, and blacklist them.
