output to DVD

Hi, this is my first time posting on here and forgive me for asking. I wonder if you guys can help me, when I render from Vegas to DVD, i usually set the Field order to None (Progressive scan) in avi file, instead of using the (Lower field first). What do you guys do, is there advantage and disadvantage of using Progressive scan? Thanks in advance for your comments.

Depends on what you expect your audience to be playing the video on.... If they will be using a TV, then you might want to render as an interlaced (choose the field to go first) video. If your customers will be playing the video on an LCD system then you can go with the progressive render.

I also am a Vegas user. I have not changed the NTSC DVD Architect MPEG render settings from their default values. One of these days I'll fidn the time to play around and do a lot of different renders.

there are many posts here pertaining to the differences of progressive scan vs interlaced...

primarily, progressive is a smaller file on output, BUT if ur source mateial is interlaced dont bother changeing as you will need to interpolate the half fields, and this "softens" the image.
If however your camera shoots in native progressive scan... USE IT..
for SD DVD, it offers the highest possible resolution for dvd delivery BUT at least when played on a projector or LCD panel, the progressive scan signal will be picked up and the playback device will run a native PS, however if the LCD picks up an interlaced source, most likely latency will start to occur as the display device deinterlaces the signal itself as LCDs and plasmas are native PS anyway
There are heaps of threads about this in the DVX and XL2 forums, best to check there..
