I have recently been purchasing and downloading movies from such sites as Amazon, mainly for the entertainment of my wife who is severely disabled. I bought two Blue-ray USB drives, and the necessary burner software from a company called ImElfin that I located on the Internet and from whom I received an activation key for the software. Then, when I first tried to burn a disk, the ImElfin software required me to enter the activation code, which it immediately rejected as invalid.\n\nI sent an email to the company's support site seeking the correct code and received no response. Two weeks later I tried again and eventually received a ticket number -\- but no further response whatever in the last three weeks.\n\nMeanwhile I managed to get the software to work after a fashion in what, I assume, was trial mode although it didn't say it was, but when I tried to burn a 5GB movie the software insisted that a disk space of 35GB was required and I had only inserted a 25GB disk. So my questions: (a) have any other members come across this company and are they legit, and (b) how is it that a 5GB movie needs a disk space of 35GB on a Blue-ray disk?\n\nI have to admit that in spite of many years programming and fixing computers I am very new to the Blue-ray business and have yet to get the hang of it, so any advice would be helpful.
