What Kind Of Preset Should I Use On Handbrake?

Okay so I have an iPod touch and I would like to convert my DVDs so I can play them on my my iPod using handbrake. I’ve already asked a question like this but people keep telling me to use iPod high rez. I checked and on my handbrake I dont have high rez, but I do have iPod legacy. Should I use iPod legacy? And also there is a preset called iPhone and iPod touch, but I’ve heard iPod high rez is the best one. Is iPod legacy the same thing as iPod high rez?
