is it possible to render HD video footage for DVDA without the video tearing? I have tried render to mpg2,avi, and even just letting DVDA handle the HD Render but all of these render with video tearing
If I understand you correctly, you are referring to the jagged edges and "shimmering", which might occur when downsizing from HD original frame size to DVD. I encountered this problem when rendering to 720 x 576 PAL from AVCHD 1920 x 1080.
In my case, I discovered that the the field order of the downsized media was different to that of the original. Setting field order to match that of the original resolved the issue.
This may not solve your particular problem, but it is worth a check.
