DVD packet writing

[John Williams <john@pond-weed.com>]

Hello,

I've got an NEC ND1300 DVD burner, and the DVD+RW patch from

    http://fy.chalmers.se/~appro/linux/DVD+RW

doesn't work on it: evidently this a firmware bug. Also this patch
conflicts with the CDRW packet writing patch from

    http://w1.894.telia.com/~u89404340/patches/packet

and stops it from working.

I've made a fix for this, which can be downloaded from

    http://www.pond-weed.com/dvd.html

With the fix, the CDRW patch works, and the same CDRW-style packet
writing can be used to write to a DVD+RW too.

If your DVD writer doesn't have buggy firmware, my patch will still
allow you to use both CDRW packet writing and the DVD+RW patch at the
same time.

John
