DTS-MA and TRUE-HD formats are not supported on the WDTV and they never will be.
They both require HDMI 1.3 hardware which the WDTV does not have.
I don't understand, is it not supported because of the software or because of the hardware ?
DTSHD is supposed to be based on DTS, contrary to Dolby and Dolby true-hd. Shouldn't digital sound be coming out through the optical output to be decoded by a home cinema ? The only problem (for DTS-HD) should be with the home cinema, not with the WDTV.
I might be wrong, but I just don't understand.
