I've been trying to watch the tennis today. All TSN channels are either stuck on a continuous loop of a few seconds or are just buffering like mad. Tennis HD was fine for around 30 mins and then just plays for a minute and buffer shows at zero. All Eurosport channels horrible buffering. It's not my internet connection (which is ridiculously fast and works perfectly with all other streaming services).
Luckily my subscription to this dog shit service expires in a few days. I won't be renewing.
