We’ve released a new version of the RadioTime Mac client to fix reliability problems. There was a problem with the failing to open the correct media player when it came time to record causing the recording to completely fail. The bug is mainly a Tiger issue, however there have been a few cases reported on OSX 10.3. The client is free, but you’ll also need to enroll for a free RadioTime account.
Please send any feedback about the client or any other problem to support@radiotime.com
