I have pictures saved on CD-R discs and thought could insert and open them with new computer's DVD-RW drive. When the CD-R disc with pictures stored on them is inserted it spins as if loading but never does, then when closing to stop the try, get message to insert a disc. Are the two formats not compatible for pictures/documents or a setting problem with the DVD drive in new PC? The DVD drive does play CD music discs. Thanks for input.
