It not refusing to get anything. HTT can get the SWF just find. The problem is
that is NOT the audio/video. It is the SWF that downloads and plays the media.
So when you open the mirror, the SWF tries to play it, from YOUR machine since
that is where the SWF is (in the mirror,) and fails of course.

If the actual media URL is on the page, then HTT can get it also with extended
parsing enabled.

Normally, it's not so can't be done.
