Instructions follow for ripping your DVDs so you can watch them on your HTC Aria. These instructions probably work for other Android devices. They should also work for Apple devices, but you should select the appropriate Apple preset for the last step instead of the one I suggest for HTC Aria.

These instructions assume you are using Ubuntu 10.10. If you are using an earlier version, just replace steps 1 & 2 with instructions from the Ubuntu restricted formats doc page.

1. sudo apt-get install libdvdread4
2. sudo /usr/share/doc/libdvdread4/install-css.sh
3. Install Handbrake
4. Open handbrake
5. Choose your source (mine was sr0, will probabaly autoselect correctly for you)
6. Use preset: Apple > iPhone & iPod Touch (for HTC Aria & probably other Androids)
