Hi everyone again!
In the meantime, I submitted similar request of clarification to the CL customer support and they promptly replied this way:
Power2Go is an all-in-one solution for all your disc burning, movie disc authoring, media conversion, and backup needs. With unparalleled support for a wide range of disc & mobile formats. While PowerProducer 6 lets you work with media files in a huge range of formats. You may also import files from your hard drive or grab scenes from existing discs to breathe fresh life to older clips by including them in your new projects.
Furthermore I include below some technical specs reg. file formats (I literally copy/paste from the CL website) for everyone's convenience:

In the
export no specs are available (to date) online, the website only lists Disc Burning/ Authoring Formats.
I think I'll go for the Power2Go suite, it doesn't seem the PowerProducer adds much features to what I need (basically burning discs such as dvd and bluray, plus basic authoring with customizable menu).
I hope this might help someone else in doubt like me.
