MCPS collects on behalf of the copyright holder, when you register that you wish to make a CD,Record etc you have to say how many copies and at what price they will be sold for (Retail or wholesale) the amount you pay is determine by the 4 main factors: Amount pressed (burned), Price per copy, number of tracks per copy, and tracks that a copyright is held for.

Working on the above, even if the CD is registered with MCPS (NOT a legal requirement) and the CDs are NOT sold there will be nothing to pay.

Manners would suggest that a) If you know of the copyright holder a letter/email to let them know what you intend to do and b) It might be nice to send them a copy of the CD. Some Copyright holder also hold the "right to first recording" if this exists then you would be open to court action.

N.B. Before a CD pressing company can/will proceed with the pressing they will require a "permission to proceed" form from the MCPS to ensure that any dues (or no dues!) have been paid.
