I beleive it gets some of the EPG from the internet and talks to home, so as others have shown it looks to be locked to ISP currently. I think the Freeview side works but not no PVR
Thats right - it'll never work outside of BTs network - it gets its entire EPG from BT servers. Recordings are also scheduled remotely - so yes - it just becomes a freeview box with no programme info, EPG or PVR facilities.
It should have been here from the start but it appears to have been abandoned. They had a lot of problem getting it working without a connection to the Vision servers.
