Due to a bug inside either the linker or glibc it is not possible
to link cdrecord and similar programs statically. If you like, I could
check again and send you the error messages.

If the ld/libc problem was fixed - may be...

cdrecord-ProDVD is one of the very first DVD-R/DVD-RW recording programs.
It started 4 years ago, when a drive was 18000 $ and a media was 70 $.

As DVD recording is not a common feature and from some bad experiences with
companies who did steel in one case e.g. cdrecord/Linux for a commercial
closed source project, I am curently not making this program OSS. It would be too
simple for companies that currently don't have DVD-R technoligy to steel the

You may check a test binary from

it writes unlimited in dummy mode and limited to 1 GB in real mode.

... don't forget to use one of the latest Linux kernels as there was a bug in 
the ISO-9660 filesystem code that prevented DVD sized media to work in Linux.

Mkisofs did recently get UDF support and passed the Philips UDF conformance test
for Video DVD media. It still has to be enhanced as it currently binds
UDF name space to Joliet namespace which is a bad idea.
