Obviously you have no idea who you are talking to! I know exactly what you are saying but the signal on the LD is an Analog signal so there is no way to get a digital copy! The ONLY (and preferable) method is to capture that analog information directly from the format it was saved to (LD) and preserve it directly in digital format without any further analog processing! As far as I understand, that is the goal of this project and there will always be naysayers like yourself but I'm sorry you cannot get a digital copy of something that was never recorded digitally!
This is the best option available.
In theory, if enough captures of the same thing were made from several different LD's then a MASTER copy could be assumed.
By your logic NO Music or Movies recorded Analog should have ever been reproduced on CD or DVD! I cant image a world where that were the case.
