Blue Sky;
The link to the original file (the one that plays in realplayer) is
here.
Right click this, and "Save Target as" or "Save Link As". This will create a file with the extension ".ram". Right click, select "open with" and choose notepad as your application. You will then see the contents of this file in notepad. In this case, the contents are a link to the full file. (I've already posted the link for you in the previous post, just right click it and save it.

).
I'm not sure why only part of the clip would be downloading...the files you are downloading are the exact same as the ones realplayer should be using.
