[mythtv-users] Mythbuntu MediaBuntu Two Options?

[nospam312]

In Mythbuntu Control Panel you can enable Medibuntu and Medibuntu
Keyring.  You can enable Medibuntu without the Keyring what is the
purpose of checking the Medibuntu Keyring option?  I have done this
and it has warning against unsafe software?  Is this a safe option to
have on and what advantages does it give over just the Medibuntu
option switched on?

TIA
