The only definitions of those acronyms I am familiar with are

Constant Bit Rate (CBR)
Variable Bit Rate (VBR)

The terms are most often associated with Asynchronous Transfer Mode (ATM) data networks. In that context, CBR is a fixed bandwidth that is guaranteed at all times. VBR is a best effort service that does not guarantee latency (delay rates) between transmission and reception. CBR is a more costly, but better for delay sensitive applications or where you want a guaranteed bandwidth.

If the acronyms mean the same in the video/DVD world, then you can assume a similar analogy. CBR is more a constant stream of signal, whereas VBR may have variable signal levels with bursts of higher bandwidth when needed.

Hope this makes sense.
