[media] doc-rst: Fix format of avermedia.rst

Browse Source 
This file is almost at the ReST format, but some things need
to be fixed for it to be parsed.

Also, the documentation there is old. So, add a notice about
that.

The purpose of an Analogue TV is to receive and display an The purpose of an Analogue TV is to receive and display an
Analogue Television signal. An Analogue TV signal (otherwise Analogue Television signal. An Analogue TV signal (otherwise

dealing with digital signals, not analogue signals and a dealing with digital signals, not analogue signals and a
composite video signal is about as far removed from a digital composite video signal is about as far removed from a digital

The DVB-T card is based around the BT878 chip which is a very
common multimedia bridge and often found on Analogue TV cards.
There is no on-board MPEG2 decoder, which means that all MPEG2
decoding must be done in software, or if you have one, on an
MPEG2 hardware decoding card or chipset.
