I'm having this exact experience. The feed will hold for a minute or two on the computer then drop. It's been steady on the iPad all night tonight though.
Mouse over the lower right hand side of the feed, and click the red LIVE button. You're welcome. -jim
I don't know about the other guys, but on my computer it goes from the live feed to the page giving the "not responding" image after a minute or two Gotta love the iPad though. It's been the real MVP for the last few rounds where I've been experiencing these glitches!
I've actually tried those. It still won't hold for more than 5 minutes on my laptop for the last three or so races. I've watched Moto3 and Moto2 both uninterrupted on my iPad though. It makes me want to say that it's my computer acting up, but I can watch anything that's been prerecorded (ex. QP1 and QP2 this morning) without issue on the computer. The only issue is when I try to watch something live through the feed. It's pretty strange imo.
This is one of my first times trying the live feed, I usually just watch the races via replay. Tonight about every 10 or 20 minutes it'll stop and I can't hit Play or Live buttons to resolve it. If I reload the page it'll pick up just fine. I'm also seeing 1-4 second jumps back, altho this isn't bothering me as much. I have my video feed set to Auto so I'm trying 540p but this usually isn't a problem with other services, MotoGP feed seems finicky no doubt. I might try a different browser, I'm on Firefox and usually watch the replays using Chrome with no problems.
I've got 50 Mbps speed and it's been locking up throughout the race. Reloading the page is the only thing that helped. It started doing this during the last couple of races, but this race was getting ridiculous.
