When I tripped on my router's power cord yesterday, l noticed something strange in PlayOn. Not only did the first item in the queue fail, but they all did. One after the other. Like dominoes. Especially since there isn't a way to re-queue all failed recordings, it is very annoying to recover from this scenario.
Suggestion: add a configuration to Settings to allow for automatically pausing the queue on the first failure or partial fail recording. Default to having this checked as well.
