I bought a double scart adapter, connected it to my tv and then connected my freeview box and dvd player to it but now the volume is really low, even when the max volume is selected on the tv and freeview box/dvd player, any ideas as to why? Also when I play a CD on the DVD player the sound is really distorted like it is too loud when the volume is low on both tv and dvd player, any ideas what's wrong?
