1. Looks like the beamer has a USB-Interface for sending commands from a PC. Do you have any information about the command set?
2. Movies should be always recognized.
@Knightro: Please extract and start SSDP.exe (Your LG TV must be on!). This will list the UDAP/2.0 answer of your TV to the SSDP request.
Then I can compare it to the values that the LG Smart TV Emulator returns. Maybe there is someting different.
