If I may pop in on this, the EULA for Video Pro X, found at
http://www.magix.com/us/eula/professional/
states (I will simplify it afterward):

"5. Using the Software and Contents for commercial purposes
5.1 Software The Software may be used for commercial purposes subject to the restrictions in clause 6.
5.2 Contents
a) The Contents may be used for commercial purposes subject to the restrictions in clause 6 if they are used to create your own work results.
This also applies to music, video or photo data as well as the corresponding templates acquired through or by means of MAGIX Products.
b) Exploitation of Contents outside the scope of personally created work, i.e. separate from the work results achieved with the Software, is prohibited in all cases. In particular, the photos contained in the templates may not be extracted and used separately. This applies to both Commercial and non-commercial Uses.
6. Prohibition to copy and rent; amendment prohibition
 6.1 You are prohibited from copying the MAGIX Product and the written documentation either partially or in its entirety. Creation of a Software copy for back-up purposes is excluded from this provision."

In simplified English, it says that you can use the "things you create" with the program for Commercial Use (selling video discs of your work, entering into Contests, YouTube Monetization, etc).
However you cannot use the pieces of the program separately and say they are your own (images, sounds, etc).
Section 6 basically says you cannot copy the program or it's manual,etc or sell those things directly as though they are your own products you have made, but I am sure you or hardly anyone else was going to start going around such a thing... but it's still there just in case.

Most Video Editing Software is the same way, where anything you make with the software is yours to sell or make money from; as long as you don't just put some samples from the program that are built in, into one little video and say it is your own work/creation, putting no creativity into it at all... then they won't like that, since it is just things plastered together that "they made"... that is really the only way you can "break" most Video Editing Software agreements (directly using what is given in them without changing them at all).

As always, John has a good approach though; to be sure, you should always contact the Vendor of any software you purchase, so you should still contact MAGIX, just to be fully safe. 

I hope it works out for you!
