The absence of an RF output from digital boxes (and DVD players) is a right pain for those of use with old sets with no AV inputs. Just as annoying are devices that output on UHF when so many old Australian sets only have a VHF tuner. Either you have to use a stand alone RF modulator to convert the baseband audio & video signals to RF, or use a VCR to do the same thing.
Generally you'll find that the four audio RCA sockets are for stereo front and rear channels. The setup menu should allow you to combine the front and rear signals into just a normal stereo signal. In this case you just use the front left and right sockets for your audio source. If you want mono, some units will allow you to set this up, and the signal is then available from the front left audio socket. Otherwise, get or make a Y adaptor to combine the two.
In the array of 4 RCA video sockets, there will be a composite output (yellow socket). This is the one you want. The other three are component signals which are red(Cr),and blue(Cb),colour difference signals and also the luminance signal(Y) which will give you a very good monochrome picture.
S-Video is again a separate luminance and colour arrangement.
The SCART connector is an ideal way to feed the baseband AV into the set; what you get with SCART cables varies; some have just composite video connections, others have the RGB (not the same as colour difference)as well. All SCART cables are/should be stereo sound. Obviously you'll need the SCART to RCA type of cable.
Those $2 shop TV's (we have the Transonics over here too) are generally fake stereo...two speakers but simply connected in parallel to a mono amplifier. When you plug in the SCART cable, just touch the audio input plugs one at a time and see if you get 50c/s hum in one or both speakers; that'll confirm whether it's stereo or not.
