I try to use NetTV from time to time but I'm still disappointed about the performance. Some times it connect to the NetTV Server and sometimes not. Then the TV Set is searching for a network to connect with the Net TV Server - but my network is always running. Only if I restart the TV it is sometimes able to connect to the internet.
The TV Set is connected by wire via Ethernet and Router to the internet. I use FW 14.095.

This behaviour is similiary to the DLNA ability of the TV Set. Sometimes running and sometimes not. But this is well known. Hope Philips is working on it.
