[Dvd-devel] Got native ATAPI DMA with linux-2.6 working

[Harald Welte]

Hi!

After merging native ATAPI DMA writing to cdrdao earlier this evening, I
also did the trick for dvdrtools-0.1.5.  It was even easier - everything
needed was merging a recent libscg (from cdrtools-2.01a19) into
dvdrtools.

So what did I do?
- rm -rf libscg/*
- copy cdrtools-2.01/libscg/* to libscg/*
- delete the cdrtools Makefile/Target files
- copy dvdrtools-style GNU Makefile.am from dvdrtools-0.1.5 to libsct/*
- apply the following trivial patch:

--- dvdrtools-0.1.5/libscg/Makefile.am  2003-01-04 22:32:10.000000000 +0100
+++ dvdrtools-0.1.5atapi/libscg/Makefile.am     2003-11-21 22:14:30.000000000

I've put the resulting tarball online at

there you go:
