The music isn't a problem, since I record it all myself. But I've been told that the transitions I've used in Cyberlink pretty much nix it for commercial use, because there is no license for commercial use. Both Cyberlink and YouTube have said this.
YouTube is getting more efficient at discovering broken permissions. For example, I paid to have a whiteboard video create for me by someone on Fiverr, and within minutes after posting it to YouTube, the music (standard boring library-type music) was flagged -- and I'm now going back and forth debating that with YouTube.
It would be awful to spend a year of my life creating tutorials only to have them revoked down the line as technology becomes more efficient at discovering copyright infringements.
YouTube claims they may look at the encoded data to see what editing program you've used, and may ask for commercial license and permissions from the editing program that you use.
So basically if you're doing this professionally, it's not worth the risk.
After writing my previous post, I did a little digging and found a program called Movavi - $70 for the business version that grants commercial license, and it claims it is the equivalent of iMovie.
I bought it, and could not believe how much quicker I could make videos, and how much higher the quality of my videos were. The program has already saved me a crazy amount of time and put out better quality videos than I've ever been able to do with PD (has slightly less options, but I can live with that until my business grows bigger).
I am only upset that I wasted 2 years with PD, and feel that they were misleading in there marketing.
