AC-3 serves DVD, cinema, and home-theater audio, whereas DTS commonly serves home theater and multichannel media systems.
For DTS-to-AC-3 delivery, plan for channel-layout and licensing requirements.
After leaving DTS, the receiving app must support the streams encoded inside AC-3, not only its extension.

DTS to AC-3 taking too long? Check available memory; long, high-resolution sources need substantially more.
AC-3 converted from DTS not opening? Test a compatible player and inspect the output streams.
Match AC-3 resolution, rate, channels, and codec to the published delivery rules.

When does DTS to AC-3 conversion make sense?

It is useful when DTS media created for surround-sound delivery must enter a AC-3 system designed for multichannel delivery.

Where is the DTS source processed?

The browser prepares AC-3 from DTS on this device instead of sending the source to a remote conversion server.
