Hi,
i8 also had this problem but found it was related to my wireless router. try using a wired connection to the ps3 asnd re-build your tw database while you are at it.
hmmmm, posting my own reply. discovery works when using a wired connection but not wireless. im using the thompson speedtouch router. oh well i'll try upgrading the firmware and then another router.
The good news: I have a new ps3 The bad news: It does not see my tv server. I have tried twonky on a terastation and a windows vista box with no joy. Nero and the intel viiv servers are discovered. i can see errors in the twonky log : 22:08:45:654 LOG_SSDP:SSDP_notify_packet ### SSDP sending: NOTIFY...
