bigchat1 , basically what paypal wants in the verification letter is to state the actual item's status.
So if you are disputing the memory capacity (eg 1GB hacked to show 4GB), you need Radioshack to verify that the actual memory chip inside is only 1GB, and not as claimed to be 4GB.
You might also need the datasheet for either Samsung or Hynix (whichever is used in your player).
