The other way is WiDi but you have to see if you have that feature.
WiFi is possible for DLNA, but for that you need something like Servio or Twonky. Apple TV is really the cure here.
I've been told that I can send movies from my Apple Macbook to my Panasonic Viera TV wirelessly but have not been able to learn how to do it.
Both are connected to my wifi and are wirelessly accessing the internet.
Any advice will be appreciated.
