I have not personally converted from Blu-ray to DVDR but according to the site:
You might say that backing up a whole Bluâ€Ray to a DVDâ€5 is not possible, just from a quality perspective, mathematically
speaking, and that your past experiences have shown that shrinking down a digital video makes it blocky and low quality. Well, that is
definitely true for MPEG2 (standard DVD compliant video). When you compress a DVD from 4GB to just 3GB even, yes, you will
notice a very visible decrease in quality, and even your low motion scenes will be blocky in areas where the colors meet the blacks.
However, with H.264/AVCDHD the results are much more resilient when they reach their compressed form. I found it hard to believe
that a 43GB disc shrunk down to 4.3GB still looked the same. I could not believe my eyes, and actually checked the standard DVD I
burnt in multiple players and on different displays to make sure my eyes were not deceiving me. Sure enough, on my 50" 1080p
Panasonic Viera Plasma TV, I cannot tell the difference between my original storeâ€bought Bluâ€Ray Disc and the DVD5 Bluâ€Ray copy
that I made. I even stood less than two feet away from the TV, and checked closely for blocks, yet I saw none. I was amazed at the
retention ability of the x264 codec, and the audio was also still crisp with the same 5.1 HD audio.
Keep in mind, that both methods I will cover still require a Bluâ€Ray player in the end.
Although one method covers how to backup to a standard DVD, we are still backing up to 1080p Bluâ€Ray files (not SD), so a Bluâ€Ray
player is still needed to play the final destination disc.
