Topic: Software testing on DVD

Problem essence the following:
Is developed by a software, it is supposed that the program will be launched and work only with DVD a disk (setting on the constant carrier is eliminated).
There are serious requirements to speed of operation of the program with DVD. Within limits, certainly.
Problem in that for productivity testing (writing DVD of a disk, check) is a fierce haemoplenty and transfer .
Especially, when on a computer is not present DVD smile
Whether there is what that of CD \DVD emulator in which it is possible to set a limit of speed of operation and to emulate time delays connected with Random Access reading arising because of positioning of heads of a drive which that would be possible  on what a disk folder.
I will be grateful, if who that prompts what that clever thoughts in this respect.
In advance thanks that fished minute of time smile
