Is the guest appearances list for RSD on the IMDb accurate?

Are the guest appearances list for The Red Shoe Diaries accurate? I ask that as the IMDb has a reputation for not having accurate guest appearances lists for TV shows (for example with "24"). I'm putting together an episode guide on the web and need to know if the guest appearances list is accurate here, before I go and add names of actors to episode guest lists which aren't already on there.
