Opening a DVD-RAM for writing results in "EROFS (Read-only file system)" (reported by 'strace'. Let me know if I can provide any further info. I'd be happy to test any fixes. Also, any chance we get proper 'DVD-RAM is write-protected' support in 2.4.x ? It'd be really nice if write()/open(O_WRONLY) would fail in those cases. Tx, Mathias
