I saw the video.
Only thing I noticed that could be a factor is that you were clicking on the option too much. Just one click and you should hear the click noise then wait.
If it still does not change menus , then I would send it back , yes.
That Server Settings menu is the one you want to try and open up, which does not need the internet connection to open.
i do not know if there is a way to load any older file on the Fuse, I have not looked into that.
i had similar issue with another model avov ,server setting dissappeared ,i sent support ticket in and they were able to fix it with update ,it did take about same time as sending it back but it has been running since.
said they fix it read http://iptvtalk.net/showthread.php?13982-Problem-with-the-Vixo-Fuse
A quick follow up for me:
Anyways, I'm still waiting to hear from Avov on my help ticket in regards to my Fuse. I have until March 7th to return to Amazon for full refund. My first thoughts are if they can fix it, then i think I will keep it.
