Okay, I'd really appreciate some help with this problem that I have - I can't view any videos or pics on some websites with my mac. If I go to youtube for example, I can't view any videos. I am completely computer illiterate and the only thing I can tell you is that this problem has gone on for some time...I installed quicktime player, and I think that worked for some time, then I tampered with the settings and now it doesnt work!!! Can someone help me? I really don't remember what I did but currently I have quicktime and whatever came with the laptop...please help!!
