I have a collection of classic blu-ray movies and I can watch it at home.But there is another problem that is how to enjoy the wonderful movies on computer when i was on a business trip without taking many blu-ray disks? 
i have the same issue with you.
xilisoft blu-ray ripper help me solved the problem and it works great.
AnyDVD HD, if you want the full ISO, and MakeMKV if you want to remux (no quality loss, just transfer the original video/audio/subtitle streams in the Blu-ray into an MKV container). And if you want to re-encode/compress, RipBot264. Ignore the fucking idiots/spambots who say that “makemkv doesn’t wurk on win8 lelelel” - they are either mentally retarded or are trying to sell you a shitty product.
