However even some open source solution such as Kodi, they already supports realtime transcoding from DTS to Dolby Digital AC3.
PowerDVD only supports downsampling to stereo, or passthrough the raw format at the moment.
Is it possible to add an option "transcode to Dolby Digital" in the future?
This will benefit a lot of users since there is no 4k blu-ray player software that support this feature out of the box.
