I don't use Main Concept, but I was wondering if it has a minimum bitrate setting and if you set yours to 0 or 2000. Also, do you use DVD-Lab? I was just wondering because I know some authoring programs hate it when the minimum is set to 0 and didn't know if DVD-Lab was one of them. I ask this because some people I know swear that using 0 is better than using 2000 for the minimum. Also, do you close your GOP or leave them open? Leaving them open is another thing that some authoring programs hate. That GOP setting is another thing that a lot of people debate on.
Thanks.
