I' am an audiophile but I don't have too much experience about blu ray.

Yesterday I have purchased the Marantz UD5005 blu ray player and I'am very sodisfate.

The player have a USB front port and can be used with an external hardisk.

I like to purchase a 4-8 TB nas and store all my dvd collection and connect it to the USB front port of my Marantz UD5005.

But I don' t sure if when I rip my Blu ray disks collections I will lose the quality.

For audio I was used EAC (Exact audio copy) and I'am sure about the result is near the perfection (is very similar to copy and paste).

About the blu ray I see different compromise, the audio and video is always compressed and I don't know when I rip to Harkisk I add other compression ... in this case I like to see the film on traditional disk.

Can someone please explain what I lose when I rip a blu ray ?

My blu ray on USB support these files format:

Video: MPEG1, MPEG2, MPEG4
Audio: MP3, AAC, WMA, AC-3

Video: WMV9, WMV9AP (VC-1)
Audio: WMA, AAC, AC-3, DTS

Video: MPEG1, MPEG2, MPEG4
Audio: PCM, MP3, AAC, AC-3

can someone please tell me when I rip a blu ray there is a software to do an EXACT copy without lose quality ?

Try this thread:

You can copy Blu-rays without further compression; quality will be the same as the original disc.

From your list, MP4 and M2TS containers are often used for this. I don't see WMV or the others mentioned as much these days, but they may be capable as well.

MKV is popular but I don't see it shown for your player.

and the video quality may not the same as the original.

if your device support(MPEG(.mpg/.mpeg/.mp4/.ts/.m2t)), you'd best just decrypt the m2ts file of the bluray disc(nothing would be loose),
i developped a program, try it and it is free
