For the past year i have been video using a Sony VX2100 and DV tapes. The resolution is very high at 720x576. I use Sony Vegas and edit using the PAL 25fps, 720x576, set to best and no qualiy loss. I can render to AVI DV which is very good although for DVD it seems that Mpeg2 is the standard. The Mpeg2 files i create that are 720x576 are simply not as good as commercial movies, do they use Mpeg2 or some other format? (as from what i have read, DVD players only read Mpeg2 and Mpeg2 is a standard that is not as good as AVI DV or Divx for example).

MPEG2 is the standard for DVDs. Quality will depend wholly upon the bit rate at which you convert your AVI files. The maximum bit rate for MPEG2 on a DVD is 8000Kbps. This will give you about an hour on a single DVD.
Also please bear in mind that the MPEG video will not look quite as sharp on a PC monitor as it will on TV.
Good luck

Something else:
Why is it Mpeg2 created from DV 720x576 source looks better then Mpeg2 vreated from Still 720x576 source (an image created in Photoshop for example).
At the moment the only thing i can think of is the interlace side of things.
DV is interlaced where as a still created in Photoshop is non interlaced. So maybe there is a way of making an interlaced still (one idea i had was to make the still 720x1152).

Did you import a compressed (eg JPG) or uncompressed image?

I prefer .BMP files as they do not have the compression issues that come with .JPG

If you haven't tried, that won't work. Interlaced frames are still 720*576, but made up of two fields in alternating lines.

So i guess there must be away of of creating stills from 720x1152 to created 720x576 interlaced stills.

No. If you really wanted to and worked out how to dot it, it would be 576/2. Most apps have something like "optimise stills".

on ur stills make sure you pick the right settings at the start, and always use RGB for screen based work, and CYMK for print based...
