hmmm ... but why the heck xolox joines all segments and checks afterwards if the overlapping parts of the segments are equal ? this is illogical ... at least to me. i'm software engineer and i would check to segments first - as everyone - because after merging all segments there is nothing to check left.

i forgot : as i wrote in a previous posting i've watched the complete movie. the mpeg4 codec is very sensible at file corruptions. nethertheless i haven't seen any bad frames.
