like i said, it all depends on how many people have the file you want. they are seeding, you are leeching. the more people seed that particular file, the quicker you will get it...depending on your broadband speed.
i also find that downloading 'vcds' are smaller files that you can burn to cd using nero, the easiest. if you burn off avi or divx to dvd...you must ensure that you are not running any other progs on your pc. a dropped peice means the whole dvd burns out of sync.
