HP Media Center/file sharing

Help! I have a HP media center on which I'm able to record a TV show while watching at the same time. My problem is this: I've saved the episode and am attempting to share with others. The file is saved in "My Shared Files" on Kazaa and also shows up under "Media Manager" on iMesh. The problem is that NO ONE can get to the files. When they do a search...nothing. My computer came preinstalled with Media Player 9 (so I can't regress to a lower Media Player). I tried contacting Kazaa and iMesh, but you can't email them. When it says "contact them" and you do, it goes to a FAQ, which isn't helping me.

Thanks in advance for any help I can get. I really appreciate it.
