Brendan, For PAL interlaced DVD I use that pipe, used when rendering YUV4MPEG stream from interlaced DVD rushs : /usr/bin/yuvcorrect -T INTERLACED_BOTTOM_FIRST | /usr/bin/y4munsharp | /usr/bin/yuvmedianfilter -T 3 -t 0 | /usr/bin/mpeg2enc -v 0 -r 32 -4 1 -2 1 -I 1 -B 384 -b 9500 -f 8 -o $1 I use CBR because my video is short enough to be burnt on 1 DVD. If it was longer, VBR would be a better solution. Options are set in order to get the best result possible. You can have a look at here for MPEG links / specs : http://www.mpeg.org/MPEG/dvd.html Video bitrate can be set up to 9800 kbits.
