[mythtv-users] Ubunto 18.04 / 0.29 export to mkv

[Andy Smith]

Hi,

I want to export some recordings to format other than DVD, I cant see
any options in the GUI under Optical DIsks -> Create Archive ->
Archive FIles.  I came from fedora where I would use nuvexport, but
that has not been available in Ubuntu for a while, so what are my best
options, assuming I havnt overlooked something obvious in the GUI?
Thanks
