DTS to AC-3

[hardy]

I have been told to convert DTS to WAV using eac3to and then use SurCode for Dolby Digital® 5.1 Encoder and Decoder. Of course this way is for getting the best results. Any thoughts? Or is it even worth converting to WAV first and then encoding to AC-3.

I have also been looking into ffmpeg for converting.

For decoding you should have the ArcSoft DTS Decoder which comes e.g. with their MediaTheatre suite.

There's no need to decode to wav and then back to AC3. Go right at it. Since AC3 only supports up to 6 channels eac3to has the "-down6" switch which downconverts 7+ channel audio to 6 channel files.

just change the output to ''.dts'' . Eac3to will extract all channel to wav file (temporary) then it will use surcode for encoding to DTS. You dont need converting to WAV first because eac3to and surcode will do all the job for you.
If you only want DTS to AC3.. you dont need surcode

Yes, only DTS to ac3. Someone mentioned MeGUI being a steady option to convert DTS to ac3

So Eac3to is what you are looking for. By default bitrate for Dts to Ac3 is 640. If you want lower bitrate, add this in the custom options: (example: -448). If you need other command, you can find whatever you want here http://en.wikibooks.org/wiki/Eac3to/How_to_Use
