WRONG!
There is only one cdrecord source. A reduced version of the source
is available under GPL.
Cdrecord-ProDVD is now nearly 6 years old!
Cdrecord-ProDVD exists since March 1998 it is about the third DVD writing
software worldwide. It has been written using the DVD-recorder #35.
The first DVD-Recorders have been made by Pioneer in September 1997,
one day after the DVD-R standard has been aproved.
Cdrecord-ProDVD has been available on request for some time as nobody would
spend 15000 Euro on a drive and > 60 Euro for a medium. In the first year,
Pioneer did build only about 2 units per day.
On October 16th 2001, I made a Test Version publically available after
Pioneer did start to sell the A03 for less than 1000 Euro. This test version
did allow to run cdrecord -V and thus reverse engineering cdrecord-ProDVD.
On October 22th 2001, a week after the test binary has been available, a
first DVD patch to cdrecord appeared. The illegal version that is found on
RedHat systems is just made by applying this completely outdated patch.
The patch itself is not illegal but it has many bugs. If somebody creates a
binary from it and don't makes clear that this is not the official cdrecord,
then he is violating the GPL.

Not true too: cdrecord development was never really suspended.
Durig summer 2003, I was mostly working on star and cdrecord development
has been slowed down for a while.
