Ummm, yes, I knew that Glenno. It was just a little attempt at humour. Obviously not a very good one.

Well, DVD could stand for Distance/Value/Days since last start. I'm sure we could make a system up out of that. How about this:
Races 1400m or longer.
Placed at last start no more than 7 days ago.
Must be $5 plus in pre post betting.
Must be only one qualifier in the race.

Have no idea how well that one would go, but it doesn't sound too bad for something I thought up in seconds.
