Can only guess at this point that you're interpreting something differently as POST beeps. The POST codes are produced while checking the system board and are before it gets to the point of selecting a boot device.

If you're able to press the option key and get to the point of selecting a boot device, whatever you are hearing is well after the time you would be getting the POST code beeps.

I cannot be held responsible for the things that come out of my mouth.

You're right, it is after POST, I didn't think of it that way. Here is the sound that I hear:

MacBook pro 3 beeps - YouTube

But I get it about 5 seconds after selecting the DVD drive as the boot.

Need to get a tech that works on these things for a living to take a look at this.

I did find a few old posts about beeping superdrives - I'd tend to agree with Stretch's analysis at this point.
The only fix I found on those old posts was replacing the system board.
However, it might be worth opening it up and unplugging/replugging the ribbon cable (cleaning the ports ?) or replacing if it's cheap enough.

That is Ram problems. Starting from the DvD is much slower thus it comes somewhat later. Maybe just re-seating the ram is enough.
