making .asx files?

[orangesuburban]

so i found on here, i think it was here, an .asx file that had a few tv channels in it.

how does that work? i googled .asx but it didnt really help. i know of a few sites that stream tv for the computer, is there any way i can turn their feed into an .ask file to use on my WX?

(if this is the wrong place to put it please move it.)
