there are a few **** tutorials on the site but alot of helpful ones.
unless you have a dvd burner you will want to go from dvd to svcd/vcd/xvcd etc.
what i would do, is go from dvd to divx, then when the dvd goes tits up, convert the divx to (s)vcd.
i dont know much about ripping dvds (since i dont have a dvd drive), but going from divx to (s)vcd is easy enough, or (s)vcd to divx.
