Here is a question for all Kazaa user experts!!! When I downloading films or movie clips using Kazaa, I noticed that certain files can be play/view using the Kazaa theater without the file being downloaded completely (or in another word 'Preview' the file). My questions are, how do I preview the file to see whether I have downloaded the correct ones? or is that impossible for certain file? and what does these files depends on to stop the download users to preview it?
