If you're using a provider like Time Warner that has well-known and longstanding issues between it and Google's caching servers, that could be your issue. Myself and fellow Time Warnians in much of NYC spent about 2 years nearly unable to play anything above 480p. Google was sending everyone from certain blocks of Time Warner to the same caching server and it would get overloaded. There were a couple tricks you could implement at the OS level that would block the overloaded Google servers and get better video, but if you weren't using a router that supported those blocks, you were out of luck on your Xbox, Playstation, etc. Note that things seem to be working better this year, though.
