I'd like to suggest to anyone that runs a hard drive automation system, that if you resort to playing CD's, look into some sort of other software solution for emergencies.
When we do maintenance on our on-air machines we use a program called ebrcart, it allows us to play the files right off of the main server, and keep 100% continuity. EBRcart plays wav, mp3, mp3, virtually whatever you want to throw at it. It's not for full automation or crossfading...but it's cheap and beats resorting to optical discs.
EBRcart was one of the few cheap solutions I could find that played mp2's without issue.
I've messed with the demo of station playlist, it looks decent. Anyone that has money riding on the on-air product, I'd still look seriously at a real player like Nexgen or SS32. Earlier poster said support is where it's really at...SS32's support is still decent and prophet/rcs is has always been swell.
