Hello All,
When configuring a Linux kernel 2.6.x series to enable the raw device support,
it states this as being obsolete and deprecated. The suggestion is to use
the O_DIRECT flag when opening the device name. I can see how this could be
possible from inside an application where the system

I take that for "any suggestions" and (again) advise DVD writer
programs like growisofs or cdrecord-ProDVD.
With growisofs i roughly use
formatter_program | \
growisofs -use-the-force-luke -dvd-compat -Z /dev/sr0=/proc/self/fd/0

It is non standard and only looks similar to cpio.
You definitely will need afio to unpack in most cases.
