Normally there are up to 6 discreet channels (5.1) on a DVD, with the exception of DTS-EX Discreet 6.1 which added another discreet channel for a total of 7 discreet channels. So if you include DTS-EX discreet then there can be up to 7 discreet channels on a DVD. I say up to because you can have as little as 2 channels and matrix them to 5.1 or even 6.1/7.1 but there would still only be 2 channels just as a 5.1 channel DVD matrix processed to 7.1 channels is still only 6 discreet channels. A DVD does not have room for the additional channels so they have to be matrix processed by the receiver so for 7.1 there are 6 discreet + 2 matrix channels.

A Blu-ray disk has space for up to 8 discreet channels so no matrix process is needed for 7.1 channels. A Blu-ray disk can have less than 8 discreet channels. If it has less, say 5.1 channels, it would have 6 discreet channels. It could also have 6 discreet channels (instead of 8) + 2 additional matrix channels to make 7.1 channels.

If it is a 9.1/9.2/11.1/11.2 channel Blu-ray disk then the additional channels are matrix processed similar to the additional channels on a DVD.
