Internet Help Please!

Hey Fellas, Hows it going? Just had a couple of quick questions I just recently downloaded XP Service Pack 2 and it modified a few things in my computer. 1) I used to be able to open up small news clips and stuff like that directly in my windows browser (with windows media player opening up a blue column on the left side of the browers). For some reason after I downloaded Service Pack 2, I cant open up the mpeg files. Occasionally it will try to open it up with quicktime. Is there any way I can get back to the old way of opening up the mpegs in the internet browser? 2) After I downloaded Service Pack 2, it makes my actual internet explorer pages almost full screen size. I used to open up multiple stories at the same time and the stories I opened up were in small browers set the size I wanted. Now, for some reason it opens up all my browsers in the big size, which slows down my surfing a lot. Previously, I could set the size and "close or "x"" out the browser and the following pages would be that size. Now I can't do this anymore. Is there any way I can correct this? 3) When I used to open up .wmv files it used to open up in my winamp video (which I thought was very convinient). After Service Pack 2, it opens it up in windows media player. Is there any way I can revert back to opening these files in winamp?? Please let me know what you all think. Sorry if these sound like super basic questions, I just thought the pros out there would know more than me. Thanks for your help. Lauren M.

Maybe this will help XP2
