Anyone getting issues with youtube when watching a video it randomly stops and you have to keep refreshing the page to get it to work again it does it on multiple browsers and on 4 different PC's i have in my house.
I have the same issue. I have no idea why that happens, but it is not your fault. It is just poor programming and whatnot from youtube. I also have the problem that some vids do not load at all. I have about 1,5MB/s download and sometimes the video does not start playing, even on 240p.
Only happens to me on my 32bit laptop when it is using a wireless connection. Probably a coincidence as well, but it seems fine when I use opera as opposed to my normal browser (firefox).
Buffering is fine for me, but I had a problem where I couldn't seek when watching the video in HD. There is a command prompt floating somewhere on the internet that adds a Firewall exception that I did, made buffering much faster.
