Media Player Classic does it for free, if that's what you're looking for... and it's very stable.
I was trying to use that myself (since I hadn't installed PowerDVD yet), but had trouble using the title/chapter navigation. I was trying to watch Shrek 2 and it gave me all kinds of fits with the ads and stuff. Might just be this particular movie, though.
I use MPC for everything else, but still haven't figured its DVD viewing out. I guess I need to better review the docs/hotkeys.
