I may be in the same boat that you are. I installed Qtella, but it never seems to connect to anything. Incidentally, the display only seems to show about 80% of the screen regardless, of resolution or orientation.
In any event, I have an idea that the issue lies somewhere in the list of servers for it to connect to. The reason that I think this is that I have both Limewire and Gnucleus on my laptop. Gnucleus can find only a fraction of the hosts that LW can. They both run and connect properly, servers are in a list for G, but I can't find a list for LW. I think if we could find out what LW looks for we could get other clients to look there too.
Hopefully there is information here that someone will find useable.
