Just spoke to Tech about DLNA not working on my Hopper (either of two) and, after mandatory REBOOT and declining a programming upgrade to include a sports package (I subscribe to America's Everything Package already), the tech said:
XXX (ID: Z7D): XXX, I will submit a report to engineering to see if the software update will be coming soon, that should fix the issue you are having, some receivers have not updated and do not have the DLNA activated at all, your's could be one of them. If you will be sure to power the Hopper off tonight the software update could occur overnight.
What an odd statement!
No discussion about HIC's or anything. I am direct connected to the router via one of the Ethernet ports on the back of the Hopper.
