It's me again

. Anyway currently the living room has one of these:
Relisys RLT1720
and one of these:
Yamada DVX-6600
The next step instead of using the frankly crappy speakers that the tv has, is to get some decent speakers going in the living room. Currently they are connected up to a cambridge amp and speakers which are big and beefy, but ideally a 5.1 setup is desired.
The tv has these holes apparently:




It also has two RCA audio-ins and a 3.5mm stereo audio-in.
And the DVD player has these holes:
There is also a freeview box and a computer wired up...
Anyway, can anyone recommend soemthing ~£100 that could cope with this system? Home AV is not my fortÃÃâ€*’©...
