I've been using the following command-line syntax structure for testing 
(with various frequencies and adapters) and streaming the full MUX.

sudo ./dvblast -u -d 239.232.232.1:3000 -f 10773000 -a 1 -n 0 -e -t 3 -v 
18 -s 22000000 -S 3

Nothing specific on the output that would lead me to believe there is an 
error. But for the sake of a sanity check I'm adding both:
