Implayer is very good looks very similar to mol2

Turns out that, as u/smashed_atom said without realising it, iMPlayer seems indeed to be the generic Android version of MyTVOnline 2 (see MOL2 For any Android Box renamed to IMPlayer )

The app is exclusive for the GTV box, it's not even in the Play Store though I guess there are methods to extract the app from the box...
