The transparent fish bit in Peru got rewound a couple of times. "They're so transparent even they don't know they exist... I'd point them out to you, but you can't see them."
Nice setup! Next upgrade (if you don't already have one) is a receiver or amp/pro with HDMI inputs for the high-res audio formats on Blu-ray (like Dolby TrueHD and DTS Master Audio). You will hear a SIGNIFICANT difference compared to the downmixed, compressed bitstream from Dolby Digital / DTS you get over toslink.
