I recently bought a Nexus 7 and I was having the same issue as flyfisher and it would also open in Mobile version like you, sometimes. Anyway, I downloaded Dolphin Browser and Dolphin Jet Pack. I changed the settings to recognise desktop mode and not android ("user mode" in Dolphin settings is where you change) and now anytime I open VIPTV it goes straight to the desktop site and not the mobile.
