well the problems goes like this :

i open lime wire , wait untill a turbo charges connection establish , then search for some certain videos , i recieve like 20 results of 2 MB files and one or two normal size file, for example i search for a music video, so i enter the name and hit enter , the normal music video is from 30 mg to 400 mg , but i recieve alot of 2 mg results and one normal result , but from a month ago on a different internet connection i didn't recieve that much of junk results .. i have an opened port in my router and i guess the router's settings are ok , so what's the problem ??
