Help with Samsung smart tv LED55

okay i just downloaded serviio and have no idea how to connect it to my samsung smart tv. there is no render profiles available.

also i have a mac pro

[zip]

can you post some screenshots of what you mean?

how do you take a screen shot on mac?

If you've set serviio up with your media all you should need to do is turn on your TV press the Source button and select serviio from the list at the top.

I have the same TV and Serviio will simply do not work (it worked one time), but never again. It will not show up in the TV, but Twonky works every time.

Router: ZyXEL P2812
Firewall: Little Snitch (accepting all connections)

Can someone help. I have downloaded 1.3 for mac and it keeps crashing or does not work at all!
