Realplayer takes a ridiculous amount of time to download a video?

ok ive been using real-player for awhile and when i first got it was sluggish for instance if the video was 10 minutes it would take 20 minutes to download then like two months ago it got really fast i mean 10 minute clip would be downloaded in 2 minutes then it went back to this sluggish pace and the only two major changes ive made to my system is i changed my anti virus to avast and i got photoshop cs5 with came all the good stuff like adobe updater (basically its a resource hog) i think there might even be an updater for the updater but ive disabled that through msconfig or at least i think i have so any thing would be nice to help me out (ps. im looking how to fix the problem with my preexisting software not to download more so i have to learn how to use something else so if your going to reffer me to try this differnt video downloader dont even bother comenting
