I'm not sure which button you mean but File/New/Movie from the menu bar will create a new movie project.   Andy 

Irwin:Thank you saby.  Unfortunately I don't speak French.  I'll try to translate and hopefully it will be helpful.  Merci.   You can ignore the French, it's just his signature, it doesn't say anything about your problem.   Andy 

By vanish, do you mean you can't find them on disk? If you are in the main Edit window and select Library, the second item down is ''Projects'' and should show your projects broken down by location. Do they show up there?  

The question asked was whether the sample project works?  

It requires PS 23 Ultimate. You can upgrade from the more basic versions within the program if you want.   Andy 

It should say something like:   Pinnacle Studio Ultimate Version 23.1.1.242 

I just played around with this. If I double click on an audio track it opens in the channel mixer; if I switch it to the Effect tab and re-open it for the same track it goes to the Effect tab. But if I open a different audio track it starts in the channel mixer. I didn't play with it more to see if that stayed with the project or ...

Dxdiag shows the highest level: It shows 12 for me too. The lower levels are shown on the Display tab: Feature levels. That's where it shows I also have 11.1, 11.0, 10.1, 10.0, etc   Andy 

Win 10 & VLC - nope, they can play OK. I don't have Pinnacle Studio 19 but I did create a MyDVD project just now and it plays back the sound perfectly.   Do you have a regular DVD you can try on your computer? That might not work either. But it's not a base problem with Windows 10.   Andy 

I don't think it's a bug. Pinnacle Studio like many other editors treats a trimmed clip as a view onto your physical clip. You had frames that happened to be black if I understand correctly. But it doesn't matter if they are black, white or the greatest image ever: They are frames. Andy
