6.1 / 7.1 surround sound formats?

by sitonmethen / November 13, 2006 4:27 PM PST

I have a Toshiba SD-7990 DVD Player hooked to a Denon receiver capable of all the cool surround sound formats (6.1, 7.1, DTS-ES and others) via a digital optical cable. If I buy HD-DVD software, will it play back all those cool formats even though my DVD player is not HD? Will my Toshiba SD-7990 DVD Player even play HD-DVD?s? If it does play HD-DVD?s will it ?down convert? to a 5.1 sound format?

Your player can not play HD-DVD's anyway there is little chance Toshiba or any of their competion will make software to allow your player to play HD-DVD's because then they would not be able to sell their new $400-$500 HD players.

. . . do you recommend theToshiba SD-7990 as a dvd player?

Hi, I got to this thread and your comments by searching for "Toshiba SD-7990 dvd player review" as I am considering getting this new unit to upconvert to 1080P and play, via the HDMI connector, my collection of standard DVDs on my new Samsung LN-S4095D LCD 1080P HDTV. I cannot find any reviews of this new unit, so would you please tell me how you rate it and if you recommend it?

As for your question reference playing next generation HD-DVD's on this unit, I think not because the laser is not blue, so it would not be able to read all the highly-compacted data on the new BluRay/HD DVD's.

Downconverting to 5.1 in relation to HD DVD formatted disks.

I think there may be a misconception here. the 5.1/7.1/7.2 etc formates refer to the audio aspects of the recording only. It does NOT involve any specific VIDEO aspects. HD DVD refers to a High Definition Video broadcast that enables your TV to receive (if it is capable of doing so) video formats in the 720P 1080P (P=Progressive scan while the "i" extension refers to interlaced modes). Most home DVD's are encoded with 5.1 channel audio capability. To this date I have not run across any DVD's at say Blockbuster that support High Definition formatting for either the Blue Ray compression or the Toshiba High Def compression, so these discussions, although interesting may be putting the cart before the horse... let's actually see how they perform in real life situations, before judging which compression will win out overall. In reality it will be up to the movie distrubutors to determine which format they will encode their disks with, and allow greater accessability to that technology in the first place. Them's my 2 cents... Big John
