Once you've booted into Mythbuntu, press Esc to exit MythTV, point your browser at and install the mythbuntu-repos package. Mythbuntu 10.10, the latest version at the time of writing, comes with MythTV 0.23, but we'll be using 0.24 for the rest of this feature, so your first step is to upgrade. Normally, you'd choose a combined front-end/back-end, a primary back-end or a front-end - secondary back-ends involve more complexity than we've got space to deal with here. It will, however, ask you the type of installation you want. We won't go through the details of installation, because it's just the familiar Ubuntu installer in a different colour. As such, it can still be used as the basis for a standard desktop, too, simply by installing a few extra packages.
MYTHTV UNRAID SETUP SOFTWARE
Mythbuntu is basically Xubuntu with MythTV added and much of the other software removed. We'll be working with the latter option, although you can still follow the rest of this if you go down one of the other routes. There are three main ways of installing MythTV: compile from source, install packages from your distro's repository on to an existing Linux system or install a MythTV-enabled distro. HD places extra loads on everything, so you'll need a lot more storage space, a faster network connection between front- and back-ends and a faster GPU on the front-end. There are DVB-S2 cards available, so if you want HD you'll either have to get a dish or be patient. While Freeview HD has been available in the UK for well over a year, there are still no DVB-T2 cards - and you can't receive HD on a DVB-T device. This reduces the amount of CPU power needed, which is important if you're running your front- and back-ends on the same machine, or want to make simultaneous recordings. The big advantage of the DVB formats is that they're broadcast as MPEG streams, so no encoding is necessary to record them to the hard drive. There are also DVB-S receivers for digital satellite, as well as various analogue cards. DVB-T is terrestrial digital, known as Freeview in the UK. Much of the UK is now 100% digital and I use PCI DVB-T cards. The type of TV receiver you need depends on your area. You can even start watching a programme downstairs and finish it in bed, because the back-end will remember where you're up to. You can have multiple front-ends connected to one back-end, so all of your recorded content is available in each room. There are other advantages to having separate front- and back-ends.
