DTS to AC3

[billbo]

I'm trying to use EmmGunn Tools (have tried the last all-in-one MKVTools 2.4.7 and AVITools 3.4.1.b1) to convert MKVs w/DTS to AVI w/AC3 and am getting files that MediaInfo and VLC say have AC3 audio, but when played back with Quicktime and VLC have no audible sound.

I know MP4 H.264/AAC is the "new" way to go, but these AVI's are for use on a dated DivX capable DVD Player.

If I use the DivX Quick option (which defaults to .mp3) these conversions work w/out any problems, I just would rather have AC3 surround.

The answer to "Do you know if your DVD Player can even read DivX/XviD w/AC3 sound files?" is that it indeed does read AVI's w/AC3 sound, as I have ripped many DVD's to XviD w/AC3 w/Handbrake 0.9.3

I have used the combination of MKVTools and Compressor (3.5) to extract and convert one MKV w/DTS to AC3 successfully but I seemed to have just been lucky as subsequent tries have not panned out.

I am posting this here as a last resort before digging out my old AMD machine and wading through way too many Windows tutorials/downloading software trial and errors...

TIA,
billbo

Try Popcorn MKV Audio Converter or eac3to to go from DTS to AC3. You don't post much here, so your assumptions don't apply here. We're not a bunch of Apple fan boys who have to use AAC. Some here use it, some don't, but few are religious about it. I'm not personally a big fan of AAC. Many of us know very well that Divx+AC3 works on any reasonably designed player that supports Divx. Again, not sure who's been pissing in your cornflakes in the past, but nothing you've talked about is likely to raise eyebrows or cause unkind comments around here.

Use eac3to µGUI for DTS to AC3 conversion. And in VirtualDubMod or AVI-Mux GUI, mux AVI and AC3.

AVIMux-GUI, eac3to, PopCorn-MKV-AudioConverter, VirtualdubMOD all seem to be workable solutions, if my OS were Windows.

Granted, with Intel Macs, it's not too hard install such things, but I was hoping for a "Mac"-centric solution without repartitioning and reformating my hard disk.
I believe this is something that someone, somewhere at sometime has accomplished without Emulating/Switching/Wrapping a program and can say "Hey, I've had this problem before, try this out 'cause it worked for me".

If not, then hopefully someone will notice "this is something that needs to be addressed for the Mac OS." ....and some great new .App, script or utility will be coded for the "Mac OS" user base.

Sorry. You even put this in the Mac forum, didn't you? Can't blame you for us not noticing that.

Maybe ffmpeg can do it on a Mac. The problem with Macs is that there's only 1 or 2 programs to do anything, so if something doesn't work for you, you're out of luck.

I've tried ffmpegX and found out that it's not entirely up-to-date:

AVITools completed the conversion, but there was no discernable audio output and original running time was 2 hours 6 minutes:

I'm currently trying out the latest release of HandBrake .

Although it's going to spit out a .m4v, hopefully it will work.
