DVD editing and rebuilding

[bxyhxyh]

I needed to add 2 DTS track to DVD and delete AC3 ones.

I've demuxed all tracks. But when I try remux with MuxMan, it gives me error "Multiplex operation failed, probably caused by excessive bitrate".

I've never created a DVD before so I maybe lost in process.
Or am i using wrong utility? Or DVD can't include 2 DTS audios?
Help me, please.

Maybe the DTS is enough larger that the resultant stream goes over the maximum bitrate?

It is ok with single DTS audio for both.
But adding 2 DTS don't work.

EDIT: It seems 2 DTS and video bitrate has exceeded 10.08 mb/s, the maximum allowed bitrate on DVD.

Hi!

I think you've misread one word that may be the cause of your problem. I believe the Muxman error message was likely, "Probably caused by an EXCESSIVE bitrate" - NOT "An EXCLUSIVE bitrate"...

EXCESSIVE bitrate" - NOT "An EXCLUSIVE bitrate"...

Yes, sorry. It was a typo.

The maximum video bitrate of the DVD was chosen with it's original AC3 audio tracks in mind. On DVD, DTS audio tracks always have a higher bitrate than AC3 tracks (DTS minimum: 768 Kbit/s, AC3 maximum: 448 Kbit/s). Therefore the combined bitrate of the original video and the new DTS audio (and subtitles if present) overshoots the maximum allowed bitrate of 9800 Kbit/s in some places.

There is another problem also: You should not (though technically you can) put DTS on a DVD if there's no AC3 with the same content of the DTS track. The reason is, DVD-players are not required to be able to decode DTS, but they are required to be able to decode AC3. If you play a DTS-only disc on a player (or through an AV Receiver) which does not have any DTS decoding capabilities, there will be no sound at all.
