Jim is right. You need to save the playlist, then access that from Theater View.
Doesn't give you what you want, but I believe its the only way to do it.
I don't think that solves the requirement at all..
The radio station publishes a fixed url where one can download a .asx file. And this .asx contains url(s) to the final content. Whereas the
outer .asx url is fixed, the
inner url(s) can be different each time that the outer .asx is downloaded. -- Because if the radio station was in a position to publish fixed inner urls, they wouldn't bother with the extra complexity wrapping them in an outer .asx file...
So, in other words, what is needed is a mechanism in MC to add the url of the
outer .asx file to the playlist. And
not to add the
inner url extracted at a particular instant from the contents of the outer .asx file. Because although this latter inner url may indeed be valid at the time of downloading the .asx, there is no guarantee of it remaining valid for for any length of time...
