In case you've got a fast enough network, you can stream (almost) live TV and recordings using CyTV (GPL). I can't tell for sure whether it works with EyeTV 500, but it does with the USB, 200, 300, and 400 versions, so I don't think there will be a problem.
The next version will use ffmpeg for integrated realtime transcoding, so bandwidth requirements will be lower (but the server Mac should be a powerful machine).
