I'm trying to rip a couple of dvd's to divx for my dad to play on his laptop. He's got a tv out, and wants to connect them to his fullscreen TV.

Which settings should I use in the export settings for it to play back in 4:3 letterbox format?

Also, does the audio automatically mix down to 2 channels with DVDx?

Also, I've got an AMD 1.4 Athlon processer, so which resize option should I use (The P4 one causes the program to crash)?

Thanks!
