Horizontal lines/offset after Sonic MyDVD authoring

[Bud15]

Captured VHS video using ATI MMC 7.7 using ATI AIW 7500. Captured to DVD compliant MPEG2 resolution. Resulting MPEG video played normally in any software viewer I tried. When I then used Sonic's MyDVD 5.2 to build menu's, edit the video, and burn it to DVD, the result had repeating horizontal blocks of lines offset from the next. From top to bottom during high motion scenes, there were 1/2 inch or so tall and full width blocks of video that were offset slightly from the next 1/2 tall block of lines. Does this from the top to bottom of the screen. Noticed this problem from within MyDVD before burning when previewing edited sections but couldn't fix and thought it might not show up on final DVD. Wrong.

Is this some kind of interlacing problem? Doesn't seem so since the alternating blocks are so tall. Can't figure out what I'm doing wrong. Any suggestions? Thanks!

Any chance you could post a still showing the problem ? It could be to do with the capture, or that the bit rate is too low during high motion scenes. Seeing it in action might help narrow it down some.

Can anyone suggest an easy way to capture a still shot from a software DVD player? I've tried screen capture programs and they only capture a blank screen. I can't figure out how to 'capture' a still with my ATI software while playing from another software player or from within the ATI software. Any suggestions? I'm trying to give some samples of what I'm talking about in the earlier posts.

You have probably checked your player to see if it can do this. If it can't, you need something that can grab an overlay. This might do the trick http://www.boumchalak.net/content/view/19/40/

Ok, figured out the capture. Here are a couple samples of the problem I'm having. These are stills of panning/motion scenes. With low/no motion, the picture is perfect. As I said, the captured MPEG2 file doesn't show this blocking so I must have done something wrong during authoring. Any suggestions.
