well... ushare is not the best thing yes...
since a few weeks I use twonkey media server http://www.twonkyforum.com/unsupported/4.4.11/
you need a key for it in the end, but you can do a trial of 30 days to test it.
the only downside for me is, that it doesnt support subtitles like .srt files
I downloaded this one: http://www.twonkyforum.com/unsupport...1-20090108.zip
you need to have windows to install it, and I think telnet should be activated as well.
after the installation you can find the software in /opt/twonkyvision
you need to make a start script manually tho
