I've used premiere pro's export to dvd to produce a disk with great picture and sound quality, but the slow mo sections appear jerky.

I've tried some different bitrate settings and changing between vbr/cbr but it doesn't seem to help. The source runs ok on premiere's monitor screen and previous vcds have all been fine.

would the slow mos be smoother if I reduced the bitrate right down to around 4000 (comprimising quality for "smoothness") or is there another solution?

cheers for any answers
