Listening to ATR live on iPad

[Cuse Fan]

I'm unable to listen to ATR live on my iPad via www.thoroughbredracingradionetwork.com (no problem on home PC). Appears as though I need an app that plays .asx files.

1). Can anyone confirm that?
2). Can anyone recommend a good app (preferably free!)
3). Or maybe I don't need an app at all and I'm just going about it the wrong way?

Any help would be appreciated - especially since it's Breeders Cup week!

Thanks,
