Connecting XBMC to Sony AV AMP STR-(DH800 / DA2400ES)

Sony AMPS (at least the ones list in title), don't seem to add 1080p/60 1080p/24 to their preferred timings, although they do fully support them.

This can be verified by adding
Option "ModeDebug" "1"
to the "Montior" section of xorg.conf, which will allow you to see the the modes which the AMP advertises.

The following are the 1080p/(60|24) Modelines for the above AMPS:

"1920x1080@60p" 148.5 1920 2008 2056 2200 1080 1084 1089 1125 +hsync +vsync
"1920x1080@24p" 74.2 1920 2560 2604 2752 1080 1084 1089 1125 +hsync +vsync

These must be used in conjunction with

Option "ExactModeTimingsDVI" "True"

in the "Screen" section of xorg.conf

Unbound DNS

Setup Unbound (validating, recursive, and caching DNS resolver) recently, and was surprised by how quick it was to setup.
Quite like it so far, seems fairly lightweight (compared to Bind), and config is straightforward.

After installing, full config is:
trusted-keys-file: "/etc/pki/dnssec-keys//production/reverse/*.conf"
trusted-keys-file: "/etc/pki/dnssec-keys//production/*.conf"
verbosity: 1
statistics-interval: 0
statistics-cumulative: no
extended-statistics: yes
num-threads: 2
interface: ::0
interface-automatic: yes
access-control: allow
access-control: ::1 allow
access-control: ::ffff: allow
access-control: refuse
access-control: ::0/0 refuse
chroot: ""
username: "unbound"
directory: "/etc/unbound"
pidfile: "/var/run/unbound/"
root-hints: "/etc/unbound/named.cache"
harden-glue: yes
harden-dnssec-stripped: yes
harden-referral-path: yes
use-caps-for-id: yes
private-address: fd00::/8
private-address: fe80::/10
private-domain: ""
unwanted-reply-threshold: 10000000
dlv-anchor-file: "/etc/unbound/"
val-clean-additional: yes
val-permissive-mode: no
control-enable: yes
control-interface: ::1
control-port: 953
server-key-file: "/etc/unbound/unbound_server.key"
server-cert-file: "/etc/unbound/unbound_server.pem"
control-key-file: "/etc/unbound/unbound_control.key"
control-cert-file: "/etc/unbound/unbound_control.pem"

Note, be sure to add allowed IP ranges in access-control section.
private-domain refers to domains where RFC1918 addresses are allowed.

Once this is done, you just need to run:
To allow control via unbound-control, then a cron job weekly/monthly to do:
wget -q ftp://FTP.INTERNIC.NET/domain/named.cache -O /etc/unbound/named.cache
