The OP wans't talking about the Playback componant he was talking about the QT MPEG2 codec that was and is still available and has been working on my computer for nearly 3 years. The playback component is a different unit, see the second pic.
You used to have to pay for it separately from QT pro, which may have changed TBH, but we purchased 40 licenses last summer.
DVDsp will transcode internally and the codec comes as part of the FC Studio pack I believe.
Transcoding is exporting.
