Stuttering and freezing videos Apple TV

Hi. Long time FulGaz rider here. The stuttering and freezing in video playback has got worse and worse this year. Every ride now has momentary stuttering and periods where it freezes for 30 second and when it comes back it races at silly speeds to catch up. I’m using a 2024 Apple TV with 1Gbs fibre ethernet and 1080p. It used to be fine but something has definitely changed for the worse this year. Downloads aren’t really that answer as the Apple TV is only 32GB so can only hold one at a time. The downloads themselves can take 30 minutes for a 20 mile ride but apps like Netflix can download a 1 hour show in 3 minutes. I’m in the UK if that makes a difference? Am I streaming from servers in Australia?
