I assume that he was refering to a computers DVD drive and CD drives. Both are the same form factor, use the same connections in your computer, have media that look (basically) the same. A DVD drive will read DVDs and CDs, where a CD drive will only read the older CDs.

Actually, the technology that went to into DVDs is much the same as CDs, the data is packed much more tightly, as we are able to focus the laser reader much more precisely now. There are other changes of course, but the two really aren't that different. Incidentally, the V in DVD doesn't actually stand for Video. Rather, it is a Digital Versitile Disc... you can put anything onto a DVD, video being the most common. Lots of computer games, (as well as Xbox and PS2 games), some computer software, and some very high fidelity audio recordings are commercially distributed on DVD.

In that respect, the analogy was spot on. Moreover, in most Asain countries the VCD player was pretty ubiquitous. If you haven't seen one, a VCD player is just like a DVD player except that it uses CDs to store the movie, where each CD holds about an hour of VHS quality video (the low quality and 2 discs per movie handocap kept them out of the US market almost all together... however, most modern DVD players will play VCDs now).

Anywho, that was a really long post to say what I had to say. Hope I didn't come across sounding liek a smart arse.
