When would you use NTSC Standard vs NTSC DV?

I've never really thought about this - I've always started my projects as NTSC DV 720x480. But now I want to make a DVD of QuickTime clips for people to use in their NLE's. I see other royalty-free footage offered by other sites at 720x486, and some others offer 720x480. I see I have both choices in the QuickTime template: NTSC DV (720x480) and NTSC Standard (720x486). So, I have two questions:

1. Given that I'm always editing Digital 8 footage to be put onto a DVD for viewing on a TV, should I always be using the NTSC - DV project settings?

2. Which format would be better to sell on a DVD? 720 x 480, or 720 x486?

If you were looking to print to analog source, then you'd want to print to NTSC Standard, IF you weren't using a DV device for the print, ie, if you had a hardware card that required 640 x 480 to print.
Digital 8, I believe, uses the same spec as 1394, and is treated like DV.
MJPEG NTSC, DV NTSC, and standard NTSC all have slightly varying ratio/sizes due to the pixel aspect, etc. Stick with 720 x 480 for almost everything you are doing for MPEG or DV.

It kind of depends on who you want to sell to. 720x480 is DV25 so if you want to sell to that market that's the size to look at. If you want to sell to Avid or Media100 users then you probably want to sell 720x486. A savvy Vegas user can always make use of 720x486 but you might want to publish some instructions to send with the disks.

Can someone fill me in, what is the difference between MJPEG and DV?

I was under the assumption that DV uses frames that are JPEG compressed and had assumed it is Motion JPEG.

I did a quick web search but didn't find any explaination.

I belive DV is susposed to get rid of stuff that isn't needed in the picture (only 1 color per pixel instead of 3 RGB) and MJPEG is what you though DV was. Jpeg normaly assumes that the the center of the picture/video is what's important so it skimps on the edges.

Did i get this right?
