Assuming it's a ps3, for video streaming I would strongly recommend PS3 Media Server.
PS3 Media Server is a DLNA-compliant UPnP Media Server.
Originally written to support the PlayStation 3, PS3 Media Server has
been expanded to support a range of other media renderers, including
smartphones, televisions, music players and more - all of which are
listed on the right. Because it is written in Java, PS3 Media Server
supports all major operating systems, with versions for Windows, Linux
and Mac OS X. The program streams or transcodes many different media
formats with little or no configuration. It is powered by MEncoder,
FFmpeg, tsMuxeR and AviSynth, which combine to offer support for a
wide range of media formats
For streaming to the Logitech Squeezebox I would give Logitech Media Server a shot.
Logitech Media Server is the server software that powers audio players
from Logitech (formerly known as SlimDevices), including Squeezebox
3rd Generation, Squeezebox Boom, Squeezebox Receiver, Transporter,
Squeezebox2, Squeezebox and SLIMP3. Logitech Media Server is the new
name for Squeezebox Server, starting with version 7.7. Before it was
known as Squeezebox Server (version 7.4 to 7.6) and SlimServer (before
7.4) Logitech Media Server is Open Source Software and written in Perl. Logitech Media Server runs on pretty much any platform that Perl
runs on, including Linux, Mac OSX, Solaris and Windows.
