The problem is that the resolution of your AVI is 528x218 which is substantially less than the 720x480 NTSC or 720x576 PAL full DVD resolution. When Toast re-encodes the AVI it is having to interpolate the additional pixels which creates a softening of the image. Basically what you have is source video that is not suitable for reasonable quality video DVD.

so if i was to change the vid using quicktime pro to 720x576 in the show movie properties menu would that improve the quality ?

also wat resolution is it best for me to use being that im in the uk and we use pal(720x576) but im looking to get the best quality possible does ntsc (720x480) offer ant benifits over pal

Stick with PAL if possible.

Here are the PAL video DVD specs:
720 x 576 pixels MPEG2 (Called Full-D1)
704 x 576 pixels MPEG2
352 x 576 pixels MPEG2 (Called Half-D1, same as the CVD Standard)
352 x 288 pixels MPEG2
352 x 288 pixels MPEG1 (Same as the VCD Standard)
25 fps*
16:9 Anamorphic (only supported by 720x576)

Toast's PAL encoder is limited to 720x576. To encode at one of the lower resolutions you'd need to use different MPEG encoding software. As for using a different application to upscale the resolution of your AVI, the problem remains the same. The software has to invent (interpolate) the additional pixels. This means making a guess that the missing pixel is an average of the ones surrounding it. This makes edges soft. With your video there would be more invented pixels than defined ones.

With a different MPEG encoder you could choose one of the lower resolutions in the above list. Toast will use those MPEGs without re-encoding to burn your video DVD. Check the Mac forum at videohelp.com for information about using other encoders.

Something you might look into is DivX. If your AVI is DivX then you can burn it directly to CD-R (see Toast Help) and play it on a DivX-capable DVD player (these are cheap). There would be no need for re-encoding in that case and the DivX circuitry makes the picture look much better than if it is re-encoded to full resolution.

Try it anyway. You might be satisfied with the results.

Oops. Sorry about that. Somehow I deleted part of my response when I posted it. I was suggesting that you might want to try ffmpegX. Use the DVD (ffmpeg) setting with the "High Quality" and "Decode with Quicktime" options enabled. Then burn the Video_TS folder it creates. ffmpegX produces better quality mpegs compared to Toast. I love Toast, but you can often see vertical lines in the mpeg-2 files produced from DivX or Xvid avis.
