Why won't YouTube play some videos?

Why wont my laptop play youtube videos anymore?

• I have an hp pavilion dv7 with an i7 processor, yes it should be PLENTY to play a dam video wouldn't you think? well it never gave me a problem till about a month ago and ever since if i watch a video on youtube...89% of them will just stop. There fully loaded. Like they pause. i cant skip forward. cant resume. The only way watch the whole thing is to refresh and skip ahead to where it froze before the video loads.... which gives me about 2 seconds >l and it will play about 50ishh seconds more then do the same thing again. i have disabled that acceleration bullcrap, cleared my cache. my speed test results are the best. and i can watch all the videos perfectly fine on any other computer in my home. help please. had this computer 4 months and have plenty of memory.

• Answer:

  Have you tried updating flash player? If you are trying to play them on IE then try playing them on Google Chrome.
