This is a "synthesized" name, this means there is a channel on Transport 
Stream ID=3 with Service ID=1 found in Program Association Table but no names 
given in Service Description Table or SDT not present at all.

As far as i understand, none of the mplex on AMC3 carries SDT.

It doesn't complain, but just let you know :)
