Hi Tim,
I have a Varicam and FCP and DVDSP and output DVDs all the time. The quality has always been excellent. If I’m in a hurry, I just output from FCP a self contained QT movie, import into DVDSP and encode it there. It is really a very easy process and delivers great results. For replication masters or the final project, I use Compressor from FCP to encode, then go to DVDSP.
The tutorials that come with DVDSP are really good and fun to learn from. There are also some really great training books(available at Borders or Barnes and Noble) that come with media. It’s not a difficult program to learn.
Good Luck,
Ron Borden
