Every time you play a cart in Myriad (v2 or 3) a log is kept of the time and place that you played it. It also stores extra information such as who was logged in to Myriad, which player was used, whether any Hardware lines were active etc. This information is needed to either generate copyright returns, and also to help diagnose problems with audio not playing the way it should.

To save space, Myriad doesn't store the name of the computer that plays the item. Instead it stores the Play Log with an \"ID\" number. Each computer has a unique ID number so it is easy for the system to work out which computer played the cart.

One thing that perhaps isn't obvious is that Myriad v2 and v3 store their
list of computer IDs differently. In Myriad v2 they are stored in a file
called Terminal.lst and there is one entry for each License that you had
purchased. The ID number you are using was known as the PowerNet ID and it is this number that is stored in the Play logs to identify which computer played the cart.

With Myriad v3 each computer running is licensed independently so there is no need to have this file limited in the same way - therefore the computers are stored in a different file called Computer3.lst. The ID that computer is using is therefore known as the Computer ID instead. Again, it is this ID that is used to identify which computer played each cart in the Play Logs.

Because the 2 files are independent, the same computer may have (in fact
usually do) have different ID numbers when running Myriad v2 and Myriad v3. When we designed the new system, we contemplated trying to keep the numbers in sync, but this wasn't possible becuase of the many other differences in the file structures and the licensing methods.

The good news is that Myriad v3's reports only ever use the new Computer3 list, so there is never any confusion over which is which.

However in some older versions of AutoTrack, the Cart Play Logs reports have been updated to read the Computer list. Newer releases of AutoTrack v3 have had this problem solved though so you should consider updating to the latest version.
