To bad the Blu-ray players make it very dificult to access the lossless codecs. How many internally decode them?
If you have a sound system good enough to resolves the nuances of master audio, you can afford the upgrade to a receiver with HDMI input.
5.1 analogue output was a nice stopgap solution for early adopters, but now receivers that support HDMI are widely available and are necessary for 6.1 and 7.1 formats anyways. Toshiba apparently agrees since they abandoned analogue out after their 1G players.
