    I have several .rm clips with the size 320 x 240 which I want to
    convert efficiently to mpeg-2 (PAL DVD)

    My first try looked like this:
    1. using EO video to convert the file to an .avi with same size
    2. using TMPGEnc to convert the .avi to mpeg-2

    The options of EO video are quite easy, there aren't so much.
    But with TMPGEnc I don't know which "Rate control mode" to choose?
    VBR_CQ or CQ? Which Bitrate, which Quality?
    My first try was with VBR_CQ. Appling different CQ values resulted in
    files of same size (and quality). What is the meaning of CQ?

    Is there any tool, any table or a rule of thumb to calculate these
    parameters from parameters of teh original file?

    Regards, Paul
