1. The picture quality of the DVD depends on how long the movie is. It should look pretty good up to about 2-1/2 hours. If the resolution of the source is much less than 720x480 (NTSC) then Toast is rescaling the video to a larger size which definitely can make it appear pixelated.

 

2. Toast is re-encoding the video from one compressed format to another compressed format. Every time a video gets re-compressed the video quality decreases. You video played directly from the Mac hasn't endured this re-compression. This is why some users get a DVD player or other video device that can play DivX videos. You can burn many AVI formats using the DVD-Rom (UDF) setting in the Data window and there is no need to do any file conversion for playback on a DivX-supported DVD player.

 

3. Toast usually gets the aspect ratio right, but you can force it to use 16:9 by going to the Custom Encoder settings window and choose the widescreen aspect ratio rather than Automatic.

What if I turn reencoding off, will that help?

You AVI is almost certainly an MPEG 4 file. A video DVD must be MPEG 2. Toast will ignore the never re-encode setting when it has to do the re-encoding to meet the video DVD spec.

 

There are many ways you can play an MPEG 4 AVI video on a TV. I mentioned using a DVD player that has DivX playback capability and burning your AVI as a data disc. There also are a variety of products such as WD TV that are hard drives that connect directly to a TV.

 

I don't know how long your video is or its resolution, but you could select Half-Pel in the custom encoder settings window to improve the encoding of fast motion scenes and then choose Save as Disc Image rather than clicking the burn button. The resulting disc image may be too large for a single-layer disc. Select the disc image using the Image File setting in the Toast Copy window and either burn to a dual-layer DVD (if necessary) or let Toast use Fit-to-DVD compression (if necessary) to burn to a single-layer DVD.

DivX worked better, now going to try image file route as well. Will that method will work in any DVD player?

 

Thanks for your help

Yes, creating the disc image (from within the Video window) and then burning it using the Image File setting in the Copy window will make a disc playable on any DVD player.
