It's not a question of the link, it's a question of than your code don't return a valid string on my computer.
ok, then just tell me why and I'll fix it
it can be some strange video title that gets broken by the shell into two (or more) arguments
try to enumerate all script arguments with WScript.Echo()
BTW your code isn't correct at all cause number of arguments depends on video format and presence of subtitles
