I may have neen unclear in my querry - please don't be confused by my mention of BD RB - it was a side-lined bit of info I brought to light
What I want to know about this scenario is...
Scenario -- I ripped a BD disc using MakeMKV and the ending MKV measured 15.3 Gbs -- then I used imgBurn to make an ISO from the MKV and the ending ISO measured 15.3 Gbs also (maybe bcz like you said--it just contains the MKV within the ISO)
With that said - is there a quality/resolution loss from the original BD to the MKV rip - and/or - to the ISO made from the MKV in imgBurn - and if I want to burn/back-up this ISO from imgBurn to a Blank 25Gb BD will it play in a consumer model BD DVD player - or only on a PC's BD optical drive
Again - sorry for the constant querries - but this is still fairly new to me - and I'm trying to "get it right"
