No, 18.04 is not a disaster, but like most upgrades, it does have its
problems.  Waiting for 20.04 will not help much.  The problem you
likely have is due to the increased network security that is being put
into things, in this case CIFS.  Older CIFS/SMB protocols are being
deprecated, so you either will have to upgrade your NAS box (if that
is possible), or tell CIFS it is allowed to use the older protocols
still.  That sort of problem will only get worse in newer versions.

When you next try 18.04, you should try first with MythTV shut down
and fix things so that you can see the NAS drive from the 18.04
system.  Having MythTV running is just making it hard to work on that
system and obscuring the real problem.
