On-Demand movies and catch-up buffers endlessly after ~20 minutes
As per title. We tried to watch the film "1917" and after about 20 minutes it collapsed into buffering and telling us to check our connections. After restarting it we were able to watch a bit more of the film until it failed again. We needed to reboot about 6 or 7 times to see the complete film.
We did wonder whether there was high demand on Friday evening and tried again the following morning with the same result.
This morning we tried watching "The Andrew Marr Show" on catch-up with the same result. Our normal broadcast services work without these failures although we do get occasional pixelation momentary bursts.
Our broadband service has good bandwidth and appears to work well.
