Try 2 things. - separately is better and using RW media is smart!
1. Don't Export! From VW, Save, close and open MyDVD. Add the VW dmsm file you saved.
2. Under Tools – Options – Render, change the setting to Software.
Let us know what works???
Having somewhat similar problems with an hour long video, I read this and experimented with it.
This is the best advice I have found as it, along with the other steps below, solved my problems of what I called fuzzy video and 'ribbony video' when overlaid by text. Also cured jerky video during movement (zoom or pan) of the camera. I would now classify the results as EXCELLENT.
3. Roxio burn used only to set up the background, buttons etc AND to make an iso file.
4. Then used ImgBurn (free download) to actually burn the iso to disc, avoiding the fill up the disc option and not using max speed. Someone said the 'fill up the disc option' never results in the best video and I used 8x even though the disc is rated for 16x.
Maybe it was only one of the steps that really made a difference (like software rendering instead of the default setting of hardware rendering) or using the saved dmsm file in Roxio burn instead of an mpg or using export in Video Wave or.... But now that I found a method that works, I will stick with it and, little by little, try to understand why it works and what steps are absolutely essential.
Thanks to all of you who helped me arrive at a solution.
