I have just acquired a Vigor 2750n. Everything works as advertised -- except the DLNA server. I follow the instructions to the letter, upload a media file to the USB disc and can see that file. But the server does not show up on my DLNA-enabled Sony Bravia. I have had iSedora running on my Mac for nearly a year with no problems, so I know that a DNLA server on my network does get through to the Sony. There are as far as I can see no detailed discussions anywhere of how to diagnose and solve problems with DLNA on the router. I have written to Draytek tech support but not received a reply. Help! Many thanks.

Good response from Draytek technical support. It appears to be a problem calling for new firmware. Given how handy it would be to move DLNA service to the router, and so not have to keep the computer running simply to serve movies etc, this would seem to be an important problem to solve.
