Give XviD a go before you give your life to DivX5Pro. It doesn't have B-frames yet, but they're not the magic bullet that some people have been portraying them as.
XviD is a GPLed MPEG-4 encoder, derived from the same base code as DivX 4/5 before it went commercial (and there's a long and bitter story lurking in the background there).
Qualitative comparisons such as that at Doom9.org -
http://www.doom9.org/codec2.htm - show that XviD compares well with both DivX 5 and DivX ;-) 3.11 (in summary - XviD retains more detail than DivX 5, and is less blocky than DivX ;-) 3.11).
http://www.doom9.org/xvid.htm - Here's the XviD DVD ripping guide, including a link to the latest Windows version of the codec. Development is fast, and new versions are released at least once a week. Recent improvements include an excellent (if complicated) new 2-pass mode.
While you're at it, you might want to download ffdshow from
http://cutka.szm.sk/xvid/xvid.html - this is a very fast Windows DirectShow filter (playback plugin) that understands DivX 3/4/5 and XviD. It's very useful when you decide to remove all of that DivX rubbish from your computer, but still want to play back DivX movies.
