how do i remove DTS from AVI, convert audio then remux..?

[snadge]

I have an AVI that has DTS 5.1 audio - I want to convert that audio... how do I do it? (any format will do just my TV wont decode DTS) - pref AC3 5.1 but anything just to get it done

thanks

Extract the dts with virtualdubmod, under streams->Stream list->demux.
Convert the dts to ac3 using eac3to.
Mux back the new ac3 to the avi using virtualdubmod or avimuxgui.


Or maybe it works directly with xvid4psp, open avi, choose format avi, under video choose copy and under audio choose ac3. Save. But I'm not sure how it handles the dts to ac3 conversion.

hi Baldrick, as always thanks for your help... whilst waiting for reply ive used AVIDEMUX to 'save' the DTS Audio then used eac3to to convert to AC3 - is this method OK..?

i will have a bash with avimuxgui now - cheers

i cant get avimuxgui to run (im on Windows 7)

also heres the log from aec3to and it doesnt look good

Decoding with libav/ffmpeg...
Remapping channels...
Encoding AC3 <640kbps> with libAften...
Creating file "D:\LOTR AC3.ac3"...
Clipping detected, a 2nd pass will be necessary. <WARNING>
This track is not clean. <WARNING>
The last DTS frame is incomplete and thus gets skipped. <WARNING>
Starting 2nd pass...

any ideas on how to get avimuxgui to work?


cheers

...also, Xvid4PSP just locks up when i choose the Video or Audio output... like its scanning the file but goes on for ever and the program freezes...

avidemux should also work fine.

Right click on avimuxgui.exe and choose properties and under compatibility enable compatibility mode windows xp and it should start at least.
