Running the default ushare package in F8 (currently version 1.1a-3.fc8) works fine for me to stream music, pictures, and videos to my PS3.
Here are the MANDITORY lines I had to change:
(it is REQUIRED that you change the default ENABLE_DLNA to USHARE_ENABLE_DLNA. The same is true for ENABLE_XBOX needing to be changed to USHARE_ENABLE_XBOX to stream successfully to an Xbox 360)
If your listening network interface is anything other than eth0, you must specify it such as below:
If you have your firewall enabled, you need to specify a static port such as below, and then open this port through your firewall:
Just a quick note, starting ushare without any profiles enabled or with the Xbox profile enabled takes just a few seconds to scan my entire file collection (8,636 files), whereas starting with the DLNA profile takes almost 10 minutes.
Hope this helps, stoo
