A program without dialogue can still be measured to have a Dialnorm value, but not with the "Dialogue Intelligence" setting on the LM100.

I don't know about the PAZ but otherwise you have it right. Be aware that few people pay attention to the specs yet with regards to commercials. I just had a client tell me that their spot sounded low compared to the surrounding spots and I had mixed this spot to -23.

I think most commercials are in the -22 to -18 range, but that's just a guess.

thank you for all of the info.
