Hey,

I'm trying to watch live streaming video on a Slackware box I have connected to a television. I can get Flash to play, but that's almost always pre-recorded (and I'm trying to watch live sports.)

The site I go to (which works on Windows) is http://atdhe.net/. They provide streams that they collect somehow, but they're in different formats. (Some are in Windows Media, some are in Real, some are in quicktime, etc.) I'm using Firefox as a browser, but I could use something else.

Beyond the default Slackware (13.0) installation, what additional software do I need?

gecko-mediaplayer (available on SlackBuilds.org) can handle all 3 of these formats.

vlc handles most video formats too. AlienBob has a slackbuild on his page.

This should be your best bet if you're running from a browser. And I'm assuming you're using the proprietary Flash plugin as opposed to Gnash..
