IMHO dts is a better sounding format anyway.
I don't know if I'll convert DTS to AC3 but I feel sound variation are more important on a DTS track than AC3 track. When actors are speaking, the sound is low but when there is action the sound is high so I'm playing with my remote several times but perhaps it's only a feeling or it's not related to DTS.
And also for a compatibility a little bit

Is correct using eac3to (dcadec) and Aften encoder.

But, talking about free soft, now is better ffmpeg:
ffmpeg -acodec libdcadec -i source.dts -acodec ac3 -center_mixlev 0.707 -surround_mixlev 0.707 -ab 640k destination.ac3
So ArcSoft is useless now to decode DTS ? Do you have a conversion commandline sample with dcadec and Aften ?

Yes for compatibility and also for the other reason (see before)

Talking about size/quality AC3 is better and AAC much better.
Talking about compatibility AC3 is better.
I don't have test AAC so I don't know about the compatibility but I could test it.

Last question, what about remapping channel ? Is there a risk to have an issue with wrong channel remapping if I convert DTS to AC3 ?

Thank you !
