A bit late, but Gspot (http://www.headbands.com/gspot/download.html) is usually my recommendation. Also never get codec packs, they only cause problems. Whenever you're in need of a codec, get only the installer for that codec. It might be more fiddly, but if something goes wrong you know -exactly- what caused it. Here's a hint : for XviD (which handles MPEG and DivX as well and is totally free, not unlike ogg vs mp3), get Koepi's distribution, I wouldn't trust any other.
