| - | The file extension ISO has also become associated with a DVD rip, or really any image of any DVD or CD. It's a misnomer, since for video DVDs, the filesystem format is UDF. I'm not a fussbudget when it comes to using correct terminology, though, so I'm not going to beat it into everyone's head that they're doing things wrong. :) I use the .iso extension exclusively.

Don't take that note as an implication of inferiority. The tools are great, but in my circumstance, does not always achieve what I want to do. |

| + | I mostly use [[ddrescue]] to rip a DVD. Here's a sample syntax: | ||
| + | |||
| + | <code> | ||
| + | ddrescue -b 2048 -n /dev/dvd dvd.iso | ||
| + | </code> | ||
| + | |||
| + | Simple as that. Once the ISO is ripped, you can access it just as you would a DVD drive: | ||
| + | |||
| + | Examples: | ||
| + | |||
| + | <code> | ||
| + | lsdvd dvd.iso | ||
| + | mplayer dvd:// -dvd-drive dvd.iso | ||
| + | HandBrakeCLI -i dvd.iso | ||
| + | </code> | ||
| + | |||
| + | And so on ... | ||
| + | |||
| + | It may be worth noting (or not) that because I rip the content this way, all of the CSS encryption is also intact. | ||
| + | |||
| + | There are other ways to get the content. Since everything in Linux is just a file, you can dump the content to a file easily enough using ''cat'': | ||
| + | |||
| + | <code> | ||
| + | cat /dev/dvd > dvd.iso | ||
| + | </code> | ||
| + | |||
| + | I really, really, really don't recommend using ''cat'' since it's ugly. There are cleaner and safer ways to copy it. If you really don't want to install anything on your box, use ''dd''. I think even busybox ships with a copy of it. | ||
| + | ==== Mounting a DVD Image ==== | ||
| + | |||
| + | For one reason or another, you may want to mount the image file directly. This is where the focus on the proper filesystem comes into play. You mount it as a UDF filesystem, not as an ISO 9660 filesystem (CDs). | ||
| + | |||
| + | Mount a DVD image to ''/mnt/dvd'': | ||
| + | |||
| + | <code> | ||
| + | mount -t udf -o ro dvd.iso /mnt/dvd | ||
| + | </code> | ||
