When I download large video files (100mb or more) they got slow, as in 0-5kbs. And then when they FINALLY get to 99% it wont finish and says waiting in line and then will say downloading but stays at 0 and wont download and it just repeats that process and will not finish. Also when i preview it, it takes like 10 minutes for it to open up in windows media player. I also downloaded quicktime to see if that helped but it didnt. Help would be greatly appreciated

You're not the 1st person to complain about this issue of large files slowing down toward the end. I would suggest you manually search for new sources. Finding new people to dwnld from may help to solve this issue.

Thanks for the help. I read somewhere that some people do that to people getting large files. I found that same file with a little less users and it goes a lot faster and solved all my issues.

Good news you solved your problem.
But not good to hear people would do that deliberately to other people. Were these T3 sources?
Thanks for the hint!
