A Network Manager problem then.  It is still flaky after years of
being around.  The command line should be able to solve that problem
though - put the settings for eth1 in /etc/network/interfaces.  These
days, Network Manager does normally see that you are manually managing
an interface and lets you do that.  But on my main MythTV box, which
is a DNS server as well, I actually uninstalled Network Manager and do
everything manually.  But I did that a long time ago when Network
Manager was really terrible.  Now it is merely bad.

If you do use eth1 again, you can then run dhcpd on the MythTV box and
let it manage IP addresses on eth1 only.  But there is a fair learning
curve to dhcpd.
