When I convert dvds (whole ones or cut chapters) to generic divx, I sometimes get big squares and really bad color shifts from one scene to the next. Using 1 pass or 3, no difference. Why?? When converting to wmv (3 pass) I sometimes get a rather long error message that basically says the bitrate is too low and the encoder has an error and the "pipeline" has been terminated. Changing quality and output size sometimes will fix this, sometimes not. Why??
