Blu-ray audio

[rockhpi]

I’ve been wanting to get a Blu-Ray player for many months now, but I’m hung up on the audio (and a little confused by the terms). I have an older home theater system (no HDMI inputs) and many of the latest players don’t decode the HD audio onboard.

Do most Blu-Ray discs come with standard Dolby 5.1 or DTS tracks? Can I connect 5.1 to my receiver w/o HDMI?

I don’t want a PS3 because of the remote control issue (I know there are workarounds but…) and I don’t want to downgrade to 2.0 audio or pay a lot for a new home theatre system, but if I can get Dolby 5.1 or DTS until I can replace my receiver then I’d consider getting the BP-D1500 or something similar.

Thanks
