i'm having a problem downloading quicktime files. this just started. now all music comes as real media. please help

I don't know what your problem is. I think you need to provide more detail of your problem. From what you have said it might just be that real player has associated itself with all your music and video files which it will try and do. If thats the problem just run real player and unassociate the file types you don't want to open with real player and associate them with the player you want to use.

i dont even have real player?? what next!!!

i'm using a mac. i cant rite click.
how can i set my default player as quicktime?

You should start a new thread about your problem and say that it's a mac problem in your title somewhere, you'd probably get more help that way from mac users.

Try opening the quicktime application and then going file/open and selecting the file you're trying to open.

Don't bother downloading .avi files as most of them don't work. They're ususally crap quality anyway. (Just my opinion).

I'm not sure how you've set realplayer as your default player. Sounds to me like someone has been tinkering. ;-)
