Horizontal Offset on Authored DVD

[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 full width blocks of video that were offset slightly from the next 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? Do I need a better VCR to play the original tapes from? They look fine on the VCR. Can't figure out what I'm doing wrong. Any suggestions? Thanks!

It's an interlacing and resizing problem. Somewhere along the line you changed the vertical resolution by something close to half -- maybe 260 or so.

Here's an interlaced 720x480 frame:



reduced to 720x260 with Virtualdub's bilinear resize filter:
