Media server recommendation

[Dan Aldrich]

Been trying to set up a uPnP/DLNA server on my old iMac-G5. 
Previously been sharing the media files with SMB. Ushare didn't work 
out, kept getting bus errors, so assumed that it was too big for the 
machine. Building MediatTomb right now and trying that.

Any recommendations for something like this? miniupmp, mediatomb, 
something I haven't thought of yet?

Thanks,
