I was looking for an app that allows you to rip DVDs and put them onto your iPod / iTunes, and I found Handbrake. I also found these instructions: http://howto.diveintomark.org/ipod-dvd-ripping-guide/ and I just want to check with someone - will this affect the movie on the DVD at all? Will it work on (potentially) protected/copyrighted discs? Are there any risks attached? Thanks!
