you guys (lilacroy,mr2channel) are wrong!!! It took me 2 minutes find out that Philips MX3700d is DVD and surr. receiver in one. God ,how I hate these all in one!!! SI-Redleg - you have no digital IN on it - so there is no way hook up your cable boxaudio thru digital. Go and return it as soon as possible and spend couple more $$ for better all in one (if you are in love with it) or better buy real surr.receiver and DVD player - I know it is more $$ but it is worth it!!!!
