As I type this I am ripping a DVD to a file that I can use on my iPod or Apple TV. I am using a great, free application called Handbrake. I’ve been using it for a couple of versions. There are tons of presets already loaded, but I always tweak them. I have ripped hundreds of my personal discs for use on my personal devices.
We also use it at church when people bring a DVD to play. We don’t play direct from a disc for several reasons, not the least of which is the lag time between hitting play and seeing the video roll. So, we rip DVDs that people bring for us to play into file formats that are compatible with our players.
I can rip a full resolution, h.264 file complete with a 5.1 audio track that plays on my Apple TV using a program that I downloaded off the internet for free. I love Handbrake.
