Here's my Reed-Solomon.
Note, a symbol for Reed-Solomon is 255 bytes. Of that, 233 bytes is
information and 32 bytes parity information.
So I set the byte packet length for the tagged stream to be 233.
Note, when I tried to add a Qt Time Sink my GRC and it hung - I suspect
there might be a problem with the Throttle.
I didn't play with the Qt Time Sink since it doesn't add any useful
information.
But I did disable the Throttle and it ran better on my i7.
Your mileage may vary.
