[mythtv-users] Setting up a backend on Ub11.10

[SiR GadaBout]

Hi,

I have a laptop running Ubuntu 11.10 Server (64-bit). It is essentially
headless and managed entirely over SSH. My plan is to attach a USB digital
TV tuner and serve live TV to my local network machines running OS X 10.6.8
and iOS5. I'd also need to be able to perform remote scheduling of
recordings.

I don't have a great deal of space on the laptop (whilst it currently runs
on a 80GB HDD, I'll eventually be migrating it to a 16 or 32GB USB flash
drive), so I'm trying to keep a tight rein on what gets installed. I'm also
trying to keep a tight rein on running services in order to keep power
requirements down (UK energy companies are raising prices all the time).

I've found several How-Tos regarding MythTV, and this seems like a good
solution. However, I'm not entirely satisfied with the number of
dependencies that are installed by apt-get, and would like to cherry-pick
only the truly required packages for my needs.

For example, a How-To from 3 years ago (
https://help.ubuntu.com/community/MythTV/Install/Server/Backend) tells me
to start by installing xmltv. This is what I get:

"The following NEW packages will be installed
 libarchive-zip-perl libclass-inspector-perl libclass-load-perl
 libclass-methodmaker-perl libclass-singleton-perl libconvert-binhex-perl
 libdate-manip-perl libdatetime-format-strptime-perl libdatetime-locale-perl
 libdatetime-perl libdatetime-timezone-perl libdigest-hmac-perl
 libemail-address-perl libemail-find-perl libemail-valid-perl
 libexporter-lite-perl libfcgi-perl libfile-slurp-perl libhtml-fromtext-perl

It seems like a heck of a lot to install just so that I can grab TV
schedules from the web.

Similarly, when it comes to the core MythTV packages, the How-To recommends
installing mysql-server, mythtv-backend and mythtv-database. What I get is
this:

"The following NEW packages will be installed
 libasyncns0 libaudio2 libavc1394-0 libdbd-mysql-perl libdbi-perl libflac8
 libgl1-mesa-dri libgl1-mesa-glx libglapi-mesa libglu1-mesa libiec61883-0

I actually discussed this with some of the devs on the mythtv IRC channel,
who confirmed my suspicions that many of the packages listed above were
not, in fact, necessary for a MythTV-Backend setup. However, because they
do not officially support a backend/frontend setup split between different
machines, they were unable to help me further.

If someone could advise me how to go about installing only the precise
packages required for my needs, I'd be grateful.

Many thanks,

S.
