TubeDigger - can you download multiple live streams?

[HorseTears]

Hi - Just DL'd TubeDigger. Sorry if this is a stupid question, but I looked at TubeDigger's FAQs and googled the question. Can't seem to find an answer. Is it possible to download more than one simultaneous live streaming video w/ TubeDigger? When I post a new URL in the box, the prior download stops. Is there no way to dl simultaneously? If so, that's kind of disappointing. Replay Media Catcher lets you dl multiple streams, but it doesn't work on all sites.
