The other option, a little less desirable, but still functional, is to get a player connected to the line in on the Play:5. What you'd need to do is take the output from your CD/DVD player and connect it to the Play:5's line in, which would require a RCA to 3.5mm cable. Alternately, you could purchase a Connect, and use the RCA input on that, but that would be an additional hardware purchase, just to get the RCA inputs.
Of course, if you have a Playbar already, and don't have it connected to your TV, you would be able to connect an optical cable to a DVD/CD player (assuming it has an optical out, many do) directly, and you'd be good to go.
