To do this just click on the wav you want so you can hear it playing and click on your "GO TO" button. When the screen pops up, click on "Show Last", the url for the wav will now show in the box.

While holding down your "Cmd" key, click on "A". This will highlight the url of the wav. Continue pressing your "Cmd" key and click on "C". You have now copied the url to your webtv memory.

Go to a transloader, you can use the one at the bottom of this page, and in the box where the url of the page shows, erase everything and while holding down your "Cmd" key, click on "V". This will paste the url you have in your memory to that box.
