Ahem ahem cough sneeze cough cough.......this flu is contagious...

So conclusion is there is for sure different quality. This should end this discussion on this thread

Of course BDR can't compare with BD due mainly to the storage space, currently BDR (50G) vs BD (50G dual layer) but I believe in the near future when 50G dual layer BDR is affordable then the gap in quality will be reduce significantly. Remember last time with DVD D9 could you actually tell the difference between Speedy ori vs Petaling Street Boutique????

You are very funny.  BDR with unauthorized movie burn/copy into it, in itself already breach the laws, why need to compare it with BD in the first place? 

You keep talking just want to compare the PQ and AQ, but you do realize you are indirectly promote or support piracy. Do you? 

bluray is digital media...containing data...i.e ones and zeros...
so 10101010101 be it on a normal disc...gold disc... pariah disc...or file format... end of the day...is still gonna be the same 10101010101....

My experience
50G BDR
PQ - Good
AQ - Good but cannot trust, Some it shown DTS-HD 5.1 but only 2CH from FL & FR.. (make me understand how good they brag, still something missing that we don't know)

25G BDR
PQ - Good
AQ - At least still got 5.1 but sometime notice the sound not that great, but don't expect much since already know this is 25G
Special feature - normally can't play as already taken away so the movie can store in 25G

One thing that above BDR annoying me is when I want to playback on other language or some features that written on the cover and realized it was not available.

Blu-ray from Amazon or imported version bought at local store (now have some Blu-ray with Local Packing which I don't have any yet)
PQ - Good
AQ - of course is good, and get everything as written on the cover.
Special feature - get everything as written on the cover
Bonus - depend on which title or which version that you bought

PQ that I say good for all this 3 kinds of Blu-ray because I can't tell major different from my eye.. May be with higher end gadget which I do not own.
