Hi Andreas,

I haven't taken the time to test your software yet but I think this is a
great step forward to help free software users in the professionnal field.

I studied the licence agreement, and didn't see anything preventing the
release of the code in free software. Yet I'm no lawyer and I would
advise you to ask the FSF (info at fsf.org) if you'd like to release the
source code as free software.

I did see however that "DDP(R) is a trademark of DCA, Inc." and that you
have to affix that notice to your software and documentation.

If you're unable to release the source code pertaining to the DDP
protocol, I'd suggest you make a closed source library and use that in
free softwares. This would allow other application (such as Ardour for
example) to optionnaly have access to the library to generate DDP
compatible data.

As an addition, I also make DVDs and it would be great if your tools was
able to deal with it somehow. For the moment, I create and author
everything using free software then master it on DLT (containing DDP
files) using a Windows workstation for the replication plant.

Anyway, thanks for sharing it with us. I'll make sure to try it next
time I send a master for CD replication.
