Media Streamer - Linux to Xbox 360 and Playstation 3

[jt at camalyn.org]

Hi List,

Can anybody recommend an equivalent for Linux that will stream media
(video and audio) to a PlayStation 3 and XBOX 360? I am thinking, MythTV
or GeeXBox? Perhaps someone might have some experience of these and
whether they are fiddly or relatively straightforward to get up and
running?

Thanks in advance,
James
