Hi Woodstock! thanks for you help last time when I had this same issue.

<pedant>Not sure I receved an answer as to whether anyone has had this working under linux. :-/ </pedant>

Is anyone in a position to spot what combination of set up details are causing the fail?
is it kernel version, libs, blu ...

It does look like this is a permanent bug in this program.
Has anyone had makemkv work under Linux?

Does any one know of any open source alternatives?

Evening Woodstock

you asked for it! :-)
