it is great that they added the ability to reencode to dd as well as dts, but we should have the option of which we prefer...i much preferred getting a reencode to dts at 1.5!!!!
is there a thread dedicated to this? i hope toshiba gives us the option back in a future firmware upgrade.
I agree that ideally the HD-XA2 should have the option of which format the player reencodes to, 640kbps Dolby Digital or 1.5mbps DTS.
I thought the G2 HD-A2 Information and Discussion thread was an appropriate place to post this design change. To my knowledge there is no other thread dedicated to the subject. However, the problem with long general threads is that they rarely focus on a particular topic, so feel free to start a new one to explore this in more depth.
I want to direct your attention to Robert George's posting #3456
on that other thread. Quoted below Robert states that the pros and cons of the two SPDIF digital audio formats has been discussed for many years.

I realize a lot of you guys are new to this sort of thing, but now that Toshiba is actually sending a Dolby Digital bitstream correctly rather then re-encoding into DTS, it now veers into territory that has been covered for many years.
First off, what will look better, a VC-1 encode at 14 mb/s or a MPEG-2 encode at 18 mb/s? Anyone that has both formats should know this answer. it is also the answer to the audio issue. DTS is an inherently less efficient compression codec than Dolby Digital. Anyone that automatically assumes DTS at 1.5 mb/s is better than Dolby Digital at 640 kb/s is simply wrong.
Dolby Digital at 640 kb/s will preserve more of the original audio than will DTS at 1.5 mb/s. Don't lose any sleep over this. Toshiba should have been doing this from the beginning.
I tried to solicit other forum members observations regarding whether they heard a difference between 640kbps Dolby Digital and 1.5mbps DTS by listening to HD DVDs that had a DTS track. Unfortunately, no forum members responded. (Perhaps if you started a other thread dedicated to the subject, you might try soliciting observations again.) At any rate, in support of Robert's assertion, in comparing tracks on the opening battle scenes on The Manchurian Candidate, 640kbps Dolby Digital seemed superior to 1.5mbps DTS. It seemed to me that the surround information was much more defined in Dolby and weakly reproduced in DTS. This was a limited test and by no means comprehensive.
