It was as late as 2007 that the by fans long awaited Director's Cut was released in Austria, which is more than 15 minutes longer. If you have great expectations in the gore-department you're as wrong as anyone who supposes a rip-off-version that only has some of the deleted scenes added into it.
Actually, Ittenbach changed the movie quite a bit, a big part of the changes only is several frames long or is made out of big editings / changed procedure of scenes which gives some of the scenes a completely different meaning. There were several long dialogue scenes added, as well, though.
An exact number of cuts was not determined. In consequence of the many intertwined changes (editings, frames-extensions, moved fades etc.) it is nearly impossible to name an exact number here. For orientation purposes, "more than 200 differing spots" should really be enough.
