Yes, that's the idea, since these null frames, absence of frames, or whatever 
they are, are so 'special', maybe is not too hard to develop a filter which 
will be able to detect and remove them, then maybe would be possible to 
convert the entire video to 24fps... or not... don't know, since the original 
ripper took the decision of make it 120fps... it must be the best choice.
sorry if I said too much nonsense :)
