You do realize that one of the lasers needed for HVD is a standard blu-ray laser? The modification they made was adding the 2 green lasers to read the holographic data. Without these green lasers it cant read the holographic ilayer.
A blu-ray disc is still based off old cd technology where all information is stored on 1 or 2 metal layers stored in the middle of the disc. HVD tchnology uses a holographic layer in addtion to 2 metal layers, which is why it needs the extra lasers. Not to mention the power out put needed for those lasers is ridiculous. So when they said "modified", they meant we changed everything to get it to work
