Solve #260

[hondek]

Not work for me, Jint returing catched error from javascript like this:

{enhanced_except_4JYBn-n-_w8_f275N6O6bRKH-2WAxb}

It not crashing script but not execute propertly descramble function.

Video IDs i tested: Za36MO1xr78, 805SMR0uEi0

@hondek it works for me, at least inserting these links on the libvideo.debug app. Anyway I think it's not a related issue. I think that youtube is progressively updating his implementation, and what you get its pseudo-random, also based on your physical location. In any case, a catchable error is always better than an uncatchable crash.
