Please note that NTFS under Linux is experimental and VERY VERY dangerous. You can (and probably will) lose data trying this.
I'd like to third this if I may, I also set it up on a box running knoppix 3.1 installed on HD (using ext3) trying to access a test box running XP Pro. I'd agree the read part works fine, I've never had a problem with that (tried it with knoppix, full debian install, mandrake and RH) . Writing to NTFS nearly completely hosed the system..nsbuttar I really would think again if I were you.

Similarly I agree with phish - I'm sure it'll get better
