Hi @davymains.
Welcome to the community and thanks for your first post, we're happy to have you with us.
I'm very sorry to hear you're having some video issues with the TV Go app, I can appreciate this must be frustrating and we apologise for any inconvenience caused.
Have you tried loading TV Go in a browser rather than the app? If so, how does the video perform? If not, please try this as it'll help us see if this is an issue with the app itself.
Have you also tried removing and redownloading the app? Sometimes this can help resolve any glitches you may be experiencing.
Let us know, thanks 🙂
