まずはいつもどおりddでiso化を試みるが、入力出力エラーが出て取り込めない。
$ dd if=/dev/cdrom of=cdrom.iso dd: reading `/dev/cdrom': 入力/出力エラーです 260832+0 records in 260832+0 records out 133545984 bytes (134 MB) copied, 39.7315 s, 3.4 MB/s
rootになって、カーネルログをチェックすると以下のような感じ。セクタの読み込みに失敗してる。これは多分コピーブロックだろう。

エラーメッセージを手繰ると、どうやら"READ OF SCRAMBLED SECTOR WITHOUT AUTHENTICATION" が出るのはコピープロテクトされたDVDをddしようとしたことが原因で、これを回避するには、一回DVDプレイヤーで再生して、その後に再度ddすればよいらしい。もう一つのエラーメッセージ"Error: Illegal request"で手繰っても何も出てこなかった。
If you encountered "READ OF SCRAMBLED SECTOR WITHOUT AUTHENTICATION" error, it means the protected dvd is locked. Open the movie with a player, play a little and pause/stop it, then run CDSpeed again.
MPlayerで1分くらい再生。正しく再生されることを確認。
$ mplayer dvd://1
その後にいつもどおりddでiso化する。
$ dd if=/dev/cdrom of=cdrom.iso 15268208+0 records in 15268208+0 records out 7817322496 bytes (7.8 GB) copied, 1386.79 s, 5.6 MB/s
mplayer でisoファイルを再生して、正しく再生されることを確認。
mplayer dvd://1 -dvd-device cdrom.iso

まずは引数とオプションの確認。ddとオプション指定の方法が似ている。取りあえずのところは、-M:完全バックアップ。-i:入力デバイス、-o:出力ディレクトリの認識だけあれば事足りそう。
$ dvdbackup -h
Usage: dvdbackup [OPTION]...
-h, --help display this help and exit
-V, --version display version information and exit
-I, --info prints information about the DVD
-M, --mirror backup the whole DVD
-F, --feature backup the main feature of the DVD
-T, --titleset=X backup title set X
-t, --title=X backup title X
-s, --start=X backup from chapter X
-e, --end=X backup to chapter X
-i, --input=DEVICE where DEVICE is your DVD device
if not given /dev/dvd is used
-o, --output=DIRECTORY where directory is your backup target
if not given the current directory is used
-v, --verbose print more information about progress
-n, --name=NAME set the title (useful if autodetection fails)
-a, --aspect=0 to get aspect ratio 4:3 instead of 16:9 if both are
present
-r, --error={a,b,m} select read error handling: a=abort, b=skip block,
m=skip multiple blocks (default)
-a is option to the -F switch and has no effect on other options
-s and -e should preferably be used together with -t
Report bugs to <dvdbackup-bugs@lists.sourceforge.net>.
で、バックアップ開始。失敗。
$ dvdbackup -M -i /dev/cdrom -o cdrom Error reading MENU VOB Mirror of Title set 1 failed Mirror of DVD failed
"dvdbackup Mirror of Title set 1 failed"で手繰ったが何も出てこない。
失敗したので、カーネルログ確認。エラー内容はddを使った場合と同じっぽい
