[MPlayer-users] Ripping

HI there guys. I've got a doubt about ripping, do not konw what to chose, 2 pass or 3 pass encoding , which one do you recommend? I've read the 3 pass has some problems when riping audio first, that can lead to an audio sync errors. After reading a while, I see that 3 pas enconding, suggest a vitrate to use for 1 or two CD, but the file that it creates is 1.4GB more than less is not 700MB or 650 or 800MB to fit in the cd. Lotta thanx.
