VM's owner (Liberty Global) does not AFAIK have a recordable IPTV box, so for the moment those on XGS-PON can only get the Stream box. In future I do expect a recordable IPTV box but I fear it will be similar to Sky's Stream in that you'll get the following after the live broadcast:
1. Content is streamed by VOD servers.
2. Content, especially Catch-up, is accessed only via the channel's app (so you'll need a logon for each).
3. Content is not available at all.
In short, IPTV means the days of being able to record every live TV broadcast are coming to an end.
