We will look into Libre.fm a bit more and see what we can do. Do you have any links to their apis or info?
Yes we definitely wan't to have Xiialive available on many different platforms. We are currently working on an iPhone version of the app.
It's because the url is not in the right format :)
It needs to end with something like .mpeg or .asf
Add any of these two to your favorites :)
By "empty" do you mean that once it starts trying to connect it gives you an error "playlist empty" or something like that? If so, then you might have to remove the stations (long press on a station and choose remove) from your favorites and then add them again. Sometimes stations can change their url so the one saved in your favorites won't work anymore. Let me know if removing and adding it again fixed your issue... thanks
This seems to be an issue with the internal stream engine :( 
If you turn it off it should work.
>settings >advanced users >internal stream engine
We'll investigate and try to fix this issue.
Thanks for your help!
There have been some issues with Shoutcast servers lately but they seem to be ok now. If you press on "top hits" or "genre" button (on menu on the bottom) twice, it will refresh the list.Try that and see if they come back. When there are issues with the servers, there is little we can do except wait :(

Try changing to the internal stream engine.

The internal engine is much faster connecting to a stream.

Well by looking at the formats they have in their website(m3u asx)  it doesn't really matter because they are just playlist. It depends on what the formats of the links inside are. There's not really a "preferred" format though. aac, asf, and ogg are the higher quality ones I believe.
Sorry for such a late replay. We have been very busy. SHOUTCast was having some issues the last few days but it seems like they have resolved it. I searched for piratestation and howard 101 and they came up on Xiialive. If you haven't already please try searching again and let me know if you still can't find it. Should work now though...
What station are you searching for?
