When I want to implement a circular buffer I generally use Lossy Queues. This allows "Get Queue Status" and "Flush Queue" to be used to peek/extract data from the circular buffer. The nice thing about this is it requires no work on your part to perform the shifting when the buffer wraps around. I'm not sure what the performance of this would be though compared to DVRs. Also a nicely created VIM (VI Macro) which does the unpacking of variant data allows the buffer to accept any data type.
