Compressor for HDCAM

Hello,

I am looking to compress my HDCAM file to a mpeg 2 dvd format. As a DVD submaster. When using compressor directly from FCP 5.0.3, I will be encoding it to a Mpeg2 Best 90min, altering the maximum bit rate to 8 bit, with a 2pass VBR. Is this an optimal setting if I have to be careful of motion jitter and fine detail as well as color reproduction? I also heard that one of the best ways to go from HDCAM to standard def video and preserve the look of HD is to do 2 steps. Convert your HDCAM to a DVCpro file and compress that into an mpeg 2. Has any heard this and tried it out. Is this true? It's an extra step, ultimately, I will have to make 2 new submasters from my HDCAM - Standard Def DVCAM and DVD.

Thanks in advance
