ShiftPWM_invertOutputs should be set to false for the TLC5916. That was an error on my website, which has been corrected now. How many 5916's do you have connected and how long are your wires? It sounds like your clock signal is missed sometimes. You can try using the push-pull line driver to improve the clock signal.

I have only a single 5916 wired in at the moment, everything is just bread boarded right now and so the wires from the arduino to the 5916 are only about 4 cm.  I'll try to add in the push-pull line driver and see what happens.

When you unzip there is a folder inside the unzipped folder.  you want only the ShiftPWM folder not the one that says something like Aug_15_ShiftPWM.

After 3 days of trying to get an Arduino Uno with a TLC5916IN with shiftPWM I still cannot get it to function properly.  I am unsure as to where the problem even stems from,  Although the code says to put ShiftPWM_invertOutputs = true for the tlc5916 when i do so my LED lights up when ShiftPWM.SetAll(0);  when set at 255 my led is still dimly lighting and blinks on and off at a steady rate.  Any intermediate value leads to the led blinking on and off in a non random pattern.  I have constructed the circuit as per the instructions on the website including decoupling capacitors.  Does the problem lie with the fact that I am using a single LED for testing rather than a common anode RGB led?  After writing the above i think it makes sense that the LED is blinking the way it does as the load would normally be split by 3 and so the visible blinking from one would correspond to a dimming effect on an RGB LED.  However I still do not understand why it the LED is on when it should be off (granted my understanding of how a common anode led functions is extremely limited)  If its simply a matter of plugging in a RGB LED case I'm going to feel very dumb about wasting so much time trying to find a problem in my circuitry.
