Channel won't play for me on P5 either.
Channel 162 Fightbox... I get playback failed message
Working on portals 2-7. Can’t check p1 at the moment, but I would assume it works there too. What device/app are you using? Using buzz 4900 here
Problem fixed, working now. ALL my fault.. I had on old version of the Fightbox data in my playlist'
I reloaded the channels from the server, and refreshed the channel. All OK
Apologies !
