1. Recording data on a pressed CD is physically impossible. Such CDs do not have a "burnable" photosensitive layer; the data is physically imprinted into the plastic, and the reflective layer is applied directly to the molded plastic.

2. Most retailers will not accept opened software, movies, cassettes, etc. for return, unless exchanged for the same item; since this is generally only useful to the purchaser if the originally purchased media is defective; the returned item is generally returned to the manufacturer rather than being resold. Many retailers adopted such policies at the behest of the publishers, who were sick of being ripped off by pirates. It's also illegal in many places to resell product that has been previously used without informing the customer. Retailers are even less likely to resell returned software it today's era of software activation schemes; if the prior purchaser had installed the software, any subsequent purchaser would be unable to do so, as the license code would have already been tied to the first purcahser's hardware. (Also, most software is sealed in a tamper-evident manner, and customers tend to be very fussy about purchasing product that has obviously been opened, whether it be software or Scotch tape.) Any retailer that DOES resell previously sold, opened software should be considered suspect anyway.
