Hello,

Got a strange problem with a DVD image I have. It has 5.1 DTS sound incorparated, or at least it should have, and also just 5.1 DD. When I burn it it will not give sound on my DVD player on the TV. But when I use my player on windows XP it will work, but only when i setup the player to 2.0 and setup the DVD in the menu from the DVD to 5.1 DTS. How in the world is that possible. Is anyone familiar with this problem and knows how to solve it?

Are you absolutely sure that your hardware DVD player has a built-in dts decoder? Not all models have one (in contrast to a Dolby Digital decoder, which is mandatory). Most DVD players can output the dts data digitally to an external dts decoder (using S/P-DIF or TOS-Link) if they cannot decode dts - then you would have to connect an A/V receiver with a dts decoder.

Software DVD players often provide a dts decoder filter (depending on the version and "flavour"), but the result will be played via analog soundcard outputs, usually only as stereo/surround even if you have a multi-channel soundcard. Or it is sent via digital output (S/P-DIF or TOS-Link) to an external decoder...

Due to license restrictions, 6-channel decoding of dts might not be allowed to software DVD players, maybe according to the license costs or in general, if I'm not wrong.

That's the whole problem...normally my WinDVD player is configured to S/Pdif output because I have a decoder which can manage DTS. But when I use my DVD player on it => no sound. Really strange!
