I have a 25 meg FIOS connection at home, and youtube is almost never good for me, it usually takes me longer to load a video than it does to watch it, the buffering part way through the weird reset glitches should I choose to watch at a resolution higher than 480. Its just a mess. Even using thier HTML 5 player in IE 9 (on the videos that run in it) I still have bad issues. Youtube is a mess, and at times it just seems like thier bandwidth is powered by a hampster in a wheel.
