Leszek, at what point are you having trouble? I have Video Easy 7 and I can insert a Monotype Corsiva title from the Video Easy font list OK. The title will start at the beginning of the clip and only last for the set duration.
I'm not a whizz on Video Easy so I don't know if you can have a title by itself, before the first video clip.
You are correct as far as I can see. At least my version of the font works. I checked with MEP as I didn't even think I had it on my system and I can load and use it.
So I checked the font's licence on my PC.
No mention of being restricted. Just 'installable' and version number. Others do have restricted licences but also show up. Only fonts marked 'Symbols' fail to do anything other than show ▭▢▢□▯▯▯▭▭▯▯□ strings.
I don't even know where this font came from as I have several programs this one could have come from.
