And when you render it, what properties are you using? That's what needs to be compared.

I just use "same as first clip", usually. Otherwise, I choose "Custom", and then choose NTSC DVD, I put quality at about 85% (though I've experimented with all kinds of quality settings to no avail), I usually keep the video and audio the same as the clip I'm working with, I almost never use smart render (though again, I've tried using it to see if it makes a difference), I've tried using both variable and constant bitrate, I've tried increasing and decreasing the max bit rate. I don't recall if I've tried ticking the "2 pass encode" option, and I don't think I've ever ticked the "DVD-VR compliant" option. Could those matter, or is just a matter of "well, try it and see"?

I usually keep audio the same as the source audio, which is usually mpeg 256 or 320.

Are these the settings you're referring to?

Yes, those are the settings I was referring to. I really don't know what might be causing the problem.

Yeah, software and computers are just funny animals. There's so many variables and such. It's something I've basically learned to live with, but I thought I'd toss it out there, in case anyone had any revelatory thoughts to share.

I do appreciate how friendly and helpful y'all have been, though!

For what it is worth at this late stage, the only time I ever experienced popping and clicking on DV clips during editing was when I had captured the video using Adobe Premiere Pro. That captures Type 2 DV. Video Studio on the other hand, seems to 'prefer' Type 1 DV. But apart from the pops during editing, the end product was always snap, crackle and pop free!

I'm intrigued, Ken. What's the difference between "Type 1" and "Type 2", and is there a way for me to choose which type I'm dealing with, when preparing to import DV into Video Studio?

Type 1 is the 'simple' version where video and audio are recorded as a single stream of data. Type 2 is preferred by the pros as it records video and audio in separate streams, though all in the same package. The video quality -- and for that matter audio as well for all that I can tell -- appears to be the same,though.

As for choosing between the two in Video Studio, I have had to hook up my trust old MV960 since it has been ages since I used VS to capture DV! When you have your camera connected and in PLAY position, then on the VS Capture screen, with it set to capture DV, you click on the Options cogwheel in the middle right of screen and choose Video Properties.

I think it is now set to Type 1 by default but the drop down menu on the screen which appears lets you choose between the two. Several versions ago, it used to be set to Type 2 by default and that caused a lot of people various types of trouble because in those days some computers simply could not seem even to capture non-garbled Type 2.
