Streaming TIVO/DVR - similar to Applian Replay A/V

[boxer]

This site is awesome. One pay program I have not been able to replace is Replay A/V from Applian.

Basically it records audio/video. The best part is you can set it to schedule a recording of a particular internet stream, like a DVR (for audio). I'd like to do this for particular radio / audio programs. Anyone know a freeware alternative? if it worked on video streams all the better.
