Guys... I seriously recommend you work with your ISP or maybe do some computer housekeeping. I think your problems more likely relate to your specific set-up or service. Put another way, I'm sitting in a rural area relying upon a small local company providing DSL (13Mbps peak speed at my location). Fiber internet for me is still a few years away, yet I have absolutely no problems with the GT site.
If it's 'all' the videos that have problems, then there must be something amiss with your ISP or personal system.
I think.
