It won't allow you to Pause / rewind etc if their is no epg data if you are running from a script which has put it into a bouquet.
There is probably a way of auto filling all of your VOD with some spoof epg as a way of getting around it but I haven't got the faintest idea of how you could do that. You'd have to make some custom sources for epgimporter I would guess.
But yes if you run your VOD through a plugin that will also let you.
