i bought a new harman kardon receiever, supposely it says it'll support dolby digtal HD and DTS HD and all that new hd audio stuff. right now im connecting my PS3 to it. using an optical cable (suggested by Magnolia Home Theater people, claiming hdmi can not pass HD audio for PS3, i actually find that true, hdmi can only pass stereo sound for ps3... yah kinda weird)
so anyways when i watch movie, i go in to the audio selection and selected DTS-HD. But when the movie start playing, on the screen it only says "DTS". soo................ how do i know if it's really producing DTS-HD sound?
oh yah the one i have is AVR-254. (<---- model just incase one of the mod or admin ask me for the model)

ok i know this is gonna be a stupid question. currently i have the harmon kardon 254 receiver running with 5.1 surround sound.
does dts-hd/dolby digital-hd actually require 7.1? everytime i read about "dts-hd/DD-HD" it always mention with a 7.1, not 5.1

The person you were talking to didn't know what they were doing if they thought an optical cable could carry uncompressed audio.
Digital coax and optical both carry Dolby Digital and DTS. Neither carries DD TrueHD or DTS-HD Master Audio (the lossless formats)
HDMI is the only way to carry the signal digitally (the other method is if your BluRay player has a built-in decoder and you send the signal through 8 analog outputs on the Bluray player into a multichannel input on the receiver, but this isn't advised if your receiver accepts HDMI and can decode TrueHD and DTS-MA, which yours can).
However, I can say that the difference is minor, so don't expect night and day differences. I've listened on two setups, and the differences are slightly more pronounced on mid-priced speakers and not as much for entry level equipment (to my ears anyway, others claim it's night and day on $100 speakers, but I don't buy it).
Multichannel PCM is the same concept as TrueHD and DTS-HD Master Audio. Uncompressed 7.1 audio. This format needs to go through the HDMI as well. Although, 2 channel PCM can be sent through the optical or digital coax cable.
And although the new formats are 7.1 capable, the most channels used in any film mix to date is 6.1 and that's still rare. The large majority of films are still mixed for 5.1
