Hi,
I have only used PD5 and just recently upgraded to PD6, so I don't know exactly what PD4 looks like or how it works. That said, I'll try to explain what I know about your 2 questions.
1- As far as I know PD5 and PD6 don't recognize QTime files, so when you try to import the files, you don't see them in the dialog box. But, you could download a trial program that converts video files - do a serch on "video converter" at
www.cnet.com.
2- If you want to "capture" video from your DV camera into PD or any other video software, you definately need to connect the camera to the computer, easiest way is with a USB cable(your dv videocamera should have come with one, check the box). If you don't have one, they are about $15 USD at any RadioSahack, Target, or any electronic retailer.
Good luck
