Did the updates twice and now version 5.0.796. Strange I had to do it twice. Now after changing MAC (HOORAY!!) still won't connect with known good URL info. I have a feeling the deleted couple of bytes from device 2 is the culprit.
It's an XRS4500. I cleared cache and reset box. Now when I go to server setting I see the MAC address top right. However, I see Portal name is Server 1, below is Portal URL and save or cancel. MAC address is not shown.
I'm sorry I forgot to mention that I'm using a USB stick plugged in to the box. The VLC media player which was pre-installed on the box. I've disabled sub titles in VLC but doesn't help.
If I plug the USB into the TV I can disable the sub titles.
