I've received a ton of good, down to earth, how to info from the tutorials on this YouTube channel:
The Sharper Turtle
You can download a complete PD 17 user manual (and other guides) here and I find it to be an invaluable reference:
Cyberlink User Guides
The heading to this forum says, "where experts meet" and as a newbie I am so glad that's true! I've been helped a lot and learned a lot here. I hope to someday know enough about PD to contribute a little myself. My tip is to read through all the topics, they all provide an opportunity to learn.
Happy Holidays to all!
