I have a Panasonic DMP-BD30 connected to a Yamaha RX-V661 receiver. Currently I have video/audio running over HDMI. I am confused about the audio format capabilities of this combination. As best I can tell, there is no way to take advantage of lossless audio formats over the HDMI or digital audio cables. Would I be better off running analog 5.1 out to my receiver? Thanks.
