We tried to watch Midsummer Murder, a fine show but we had to wait for buffering at least 15 times, sometimes once every minute and one half for ten minute spans. It took more than 2 hours to watch a 1hr 36 minute episode. This doesn't happen with other apps so I have to conclude that the problem is BritBox. Addendum: We changed to a fiber optic, 500meg network 2 days ago. Britbox continues to buffer while all other apps work well. Britbox continues to be a major source of annoyance.
