Thanks for letting us know about the issue you're experiencing.
Did you restart your Roku device before reinstalling the channel? That step is crucial when performing the troubleshooting. If you haven't tried the suggested order (remove > restart > reinstall), we would recommend giving it a shot once again. We also suggest doing the restart from the Settings menu by navigating to Settings > System > Power (If you do not see a Power submenu, skip to the next step.) > System restart.
Re: BBC iPlayer bug causing freezer on iPlayer start
My two Roku 3930X have worked brilliantly for 1.5 years with BBC iplayer. In the last couple of months most catchup programmes crash half way through (sometimes sooner). Usually subtitles and audio continue. The video looses lipsync first and then crashes.
Curiously it only seems to affect stand alone catch up programmes. "Watch from start" delayed live streaming never seems to crash, even if I watch it for many hours.
I'm sensing a bug, but is it iPlayer or Roku? Any ideas?
I'll try the unistall / reinstall channel as mentioned here first.
Have you checked the other channels installed on your Roku to see if the same issue will occur? Also, how are you powering your Roku device? Is it connected to the USB port of the TV or to a wall outlet?
Please let us know. We'd like to know more about how we can help.
If the issue persists from one channel after attempting the suggestions above, videos from other channels play fine, contact the channel provider's customer support team to report the issue and get help.
Channels on Roku are maintained by the channel developer themselves. In this case, there's likely an issue within that specific channel that needs to be addressed with an update from them.
As @RokuKariza-D mentioned, we would recommend removing the channel from the Roku home screen by navigating to the channel tile, pressing the * key on your remote, and choosing 'Remove channel'. Then restart your device from Settings>System>System restart. Once your player starts up again, add the channel back once more.
If the issue remains unresolved, I'd recommend reaching out to BBC directly to report the issue and request additional support. Many channels on the Roku platform are developed and maintained by the channel provider directly, and they'll be able to best assist. If other channels are working correctly, and you only experience this issue on the BBC channel (app), that is likely an indication that the issue lies within that particular channel. In these cases, the channel provider will need to investigate the issue in order to help resolve it.
