I've just had my new V+ box installed and connected to my TV via HDMi. I have connected the red and white audio in from my 'old' DVD player (Philips MX3800D) to the tv via scart to scart adapter thats fits in to Ext RGB on TV. I can't get sound from the speakers, although I can hear something (not audibles, more of a hissing) coming through when I crank up the vol to the max. I've set the sound source on TV to External Speakers but no joy. Anyone got any ideas what I may have done wrong? I've checked the speaker connections and they seem ok. Thanks
