Blu ray player decoding from external sources?

[hodgo]

Hi guys,

I have a roksan kandy stereo amp & matching 3 channel amp and recently ditched a DVD player with 5.1 analogue outputs. I've a new flat screen with hdmi outputs only and will get a blu ray player soon.

I want to keep my amps as I have trialled latest Sony av amps for ease of connectivity and features but wasn't impressed at all with the sound quality. So....if a blu ray player has hdmi inputs can the internal decoding be used from a TV feed which I can use with my current amps with 5.1 outputs?

Thanks
