I think that the two statements above agree?

Anyway, most data streams are type complex, float, int, short, or byte. 
In this case the vector length for the file sink is always 1. Examples: 
usrp source, signal source, noise source...

Sometimes, you have blocks that output an ARRAY/VECTOR of complex, 
float, int, short, or bytes for each sample. So each sample is an 
array/vector of numbers. Examples: gr_add_vcc, gr_fft_vcc... In this 
case, the vector length parameter >= 1.

Makes sense? Is the setting of vector length = 1 not working?
