Philips BDP7600/12 + Nexus S

Hello

I want to use the MyRemote-App but I can't find the Blu-Ray-Player with my Smartphone.

My Nexus S:
Android 2.3.6
MyRemote-App V. 1.0.4

Blu-Ray-Player:
Firmware: 1.35 (latest Firmware)

They both get the IP from our HomeServer DHCP. And they are in the same Network using W-Lan. So they have the same Network Prefix and a different Host Number (of course). I have a Devolo 200 AV Wireless N which provides the wireless Internet Access.

What can I do?

Thanks in advance
