That looks like chroma shifting to me, although the only filter I know that corrects those kind of issues (chromashift) can only correct RGB shifts IIRC. If it's not chroma shifting, you could try searching the Doom9 forums for DeHalo_Alpha, it's one of the best halo removers I've ever seen.
Laserman, is the Pioneer LD-V8000 that good? How come it doesn't get more recommendations around here then?
