<pre wrap="">I'm not exactly sure how MythTV handles DNS lookups, but I can
understand why SSH takes so long when your name resolution is down.
Most SSH servers are configured to reverse-lookup the clients that
connect to them for logging purposes. If DNS is down, this process
will have to timeout before you receive the login prompt...
Perhaps Myth is attempting to do reverse-lookups as well?

It could possibly be mysql attempting a reverse look-up as well I suppose.
In any case, if somethings trying to do so, it may well be that, when the
Internet DNS is working, it's simply failing the look-up of the LAN address
immediately, but when the Internet/DNS is down, it's taking a long time to
timeout.
I'd try adding all you LAN host names and ip addresses to /etc/hosts on the
myth boxes.
