When makemkv is dumping to mkv the file is NOT playable until the end
of the dump. They put rubbish in the start of the mkv file during the
rip and then write a header at the end. (this is true in relation to a
bluray anyway, I haven't looked at a dvd file during the dump.)

makemkv WILL however stream a bluray in decrypted form without dumping
to hard drive.

There is, I am told, an xbmc addon to make use of makemkv in stream
mode to play blurays on the fly.

makemkv on linux will export either on unencrypted mkv of any title on
the bluray, or an unencrypted copy of the entire bluray disk structure
on hard drive, or an encrypted copy of the entire bluray disk on hard
drive. I don't think it is any different to the windows version in
this respect.
