All streams on Sopcast can be viewed with VLC, additionally, sometimes VLC can stream a few seconds or more ahead of what shows up in Sopcast itself, which can help reduce your lag between the stream's source and when you watch it.

To use VLC, download VLC at http://www.videolan.org and install it , then start the Sopcast stream and let it buffer. Then open VLC, go to Open Network Stream, select HTTP option, and type in 127.0.0.1:8902 (if not working, try port 8912). You MUST leave Sopcast running; closing Sopcast closes the stream. If the stream gives sound in both VLC and Sopcast, mute the sound on Sopcast, or try to hit the refresh button so the Sopcast screen goes blank, but the VLC screen stays intact.

I hope this works for you.
