Is DNAS+ compatible with Centova? I assume I'll just need to replace the srvcast (or whatever the name is) with the DNAS+ version.
Is anyone currently doing this?
What is the best way to schedule a playlist to play hourly? Is it to create 24 ad playlists on the hour?

We're always trying to support the latest official Shoutcast release, as soon as possible.

With that said, Shoutcast 2.4.7.256 is the currently supported version and we don't plan on supporting any experimental / test Shoutcast builds that might be provided to certain people, between stable version releases.
