LG HB45E connect to 2 media players?

Good morning,

I'm loving the design and picture and sound quality of my HB45E - but having huge trouble trying to connect my 2 media players to it (films and music). How can it be done?? I was thinking of HDMI switch to connect them all to TV, however I still have to connect the 2 media players to the DVD player, to get the sound through speakers.

Choices seem really limited - my media players have following outputs: usb, combined video/R/L, combined Pr/Pb/Y and coaxial.

Many thanks for any ideas.
