I added the fields/ directory to the link above, which contains the requested fields. BTW, here's what happened when i extracted the fields: [EMAIL PROTECTED] work]$ lav2yuv -f 10 yose.avi | y4mtoppm | pnmsplit - pnm/image%d.pnm pnmsplit: WRITING pnm/image0.pnm INFO: [lav2yuv] DV frame 0 len 120000 INFO: [y4mtoppm] input stream parameters: INFO: [y4mtoppm] <<< frame size: 720x480 pixels (518400 bytes) INFO: [y4mtoppm] <<< frame rate: 30000/1001 fps (~29.970030) INFO: [y4mtoppm] <<< interlace: bottom-field-first INFO: [y4mtoppm] <<<sample aspect ratio: 10:11 INFO: [lav2yuv] DV frame 1 len 120000 That confirms my feeling that it's a bottom-first stream. > > It seems like it's a "bottom first" video stream (see image0 and > > image1), but otherwise it's ok.

Based on the principle "no one is going to help me if i'm not helping myself a little bit", i did the following: I took only the first AVI file in the DV directory, which has approx 2 minutes worth of video (out of the total of 60 minutes). I converted only that file to DVD and SVCD, in order to speed up the process. I created three different DVDs: - default field order settings (no -z) - using -z t - using -z b I then created three different SVCDs: - default field order settings (no -z) - using -z t - using -z b I then went to a local computer/hardware store and pretended i was choosing a DVD player by testing it with "home-made DVDs". :-) I think i tried out like 10 different DVD players, of about 4 different brands (Panasonic, Akai, Hitachi, and some underdog type of company that i don't remember). The results were identical no matter which DVD player, no matter whether it was DVD or SVCD: - all disks created with "-z b" were perfect - all other disks experienced juddering The weird thing is, one year ago i created quite a few SVCDs, using same parameters (i came up long time ago with some SVCD scripts that i keep using ever since) and those disks have no juddering! Obviously, something changed since last summer.
