I'm guessing that it may be an abbreviated version, similar to how Nero has basic versions of it's full Nero Burning ROM with their Suites. Edit: On second thought maybe there is no more feature-rich version, as the screenshot on their site for 'Burning Studio 6' doesn't look different. In any case they all appear to be basically a mimick of Nero Suite, which can also be bought for very cheap (I've also seen it free at times online, not as a download though).
