I bought CSI DVD (first season) when it was on sale (half off) but can't return it. It said it is closed captioned. When I played it and there is no closed caption. I notice this writing on the box: "These discs were created in compliance with applicable DVD specifications. Certain advanced features may not play on all machines." Does that means closed caption is an advanced feature?? If so, what machine it will play on?? My VCR/DVD combo is Toshiba (2005). Thank you for any help.
