Do you have rw-permission on /dev/sg4 ?
I run all command as root, just to be safe:
crw-rw----    1 root     disk      21,   4 Sep  9  2004 /dev/sg4

Maybe one could learn more from

report its SCSI commands to a log file named
 /tmp/libburn_sg_command_log
..I notice that it would be better to insert
                       fflush(fp);
before the two occurences of
                       fpcount++;

I understand this stall can be interrupted by Ctrl+C ?
Yes.
