Burning Blue-ray DVDs

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.

I 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.

Meanwhile 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?

I 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.

 

Considering the company could not be bothered to answer your support request I wouldn't say they are entirely legitimate...

 

ImElfin doesn't ring any bells with me -- although they certainly do now!

CyberLink Power2Go v8 works for me as a DVD/Blu-Ray burner, and CyberLink PowerDVD v15 for watching DVDs and Blu-Rays. (There are later versions of these programs for Win 7-10. These work on Vista.) They aren't free, but Cyberlink seems to have a sale every couple of months. And reviews seem to like them.
