Looking at video tutorial : "Basic Tutorial 9: Installing and Configuring TwonkyMedia server for PC or Mac" , it happens to me that Twonky should see my TV automatically, doing nothing, but, in my case the "media receivers" list is empty, although my TV tells me that the home network is on.
I'm connecrtd with two Belkin CPL, one at the back of my TV with ethernet cable, the other is, either at the back of the iMac, or connected to my Internet box, also with ethernet cable.
I tried both connections and in both cases, the TV told it was connected to the home network, and in both case the window "media receivers" in Twonky stayed empty.
On the CPL all the three lights : power, ethernet and CPL are green.
Do not see what I can do more.
Thanks for help.
