still offer the free (1.6) version.
Zara has worked well for my over-the-air signal.
I'm using ZaraRadio under WINE in Ubuntu Linux. Have to admit, it has some bizarre quirks (the PLAY button does not appear when a song is playing, when changing a single file in the EVENTS folder, I have to readjust the start time. And when I click on View, the drop down menu will freeze on the screen when the system is playing. Even when I minimize to the bottom toolbar.) Otherwise, it functions and very well. But I really wish ZaraRadio or somebody can make a version that runs only on Ubuntu/Debian Linux. It is the fastest growing operating system in the world. And it's FREE.
Campcaster and Rivendell are a wee bit complex because they don't install from .deb files (the Ubuntu answer to the Windows .exe install) And code hashing all night with compiling files in Terminal isn't my thing. It's nice, because if you're really good at it, you can even IMPROVE the software to make it run exactly the way YOU want it to (that's the BEAUTY of open source Ubuntu Linux.) I just don't have the will (or time) to really hit the e-docs and tutorials the way I REALLY SHOULD (who knows what I could turn that lowly Totem Media Player into, an all-in-one SUPER radio/TV automation system?)
