I checked my channel list for the AZBox in Maz 3.0 and while it did give the NIDs, I don't know how accurate it is. It listed OETA, PBS E/W, and PBS Create mux as 0, LPB as 1, and Montana PBS as 65535. When I used the SharpC Channel Master program on a list for my Pansat 3500SD (list made before I moved the satellite to the AZBox), it doesn't seem to list the NIDs, as every channel (on all satellites) was listed as 0. If you can find a copy of SharpC Channel Master (while their site is still there, it doesn't seem to work) you could try it with a channel list from your Coolsat and see if it lists the NIDs.
