Link, comment.

http://www.lg.com/us/blu-ray-players/lg-BP200 shows it has the digital out but not Optical.

http://www.amazon.com/gp/bestsellers/electronics/280341/ref=pd_zg_hrsr_e_1_4_last and down the list to find a converter for your stereo I see http://www.amazon.com/AGPtek-Digital-Optical-Converter-Adapter/dp/B005DIRI6I/ has both optical and coax input.

BE AWARE YOU MIGHT STEP INTO A LIP SYNC ISSUE. It's widely discussed why and how to mitigate it so I'll stop here.
