Thanks to the developers for the tool. It does major its job perfectly. BTW, from the user point of view there is missing one critical feature for me. It's progress bar or time indicator. I'm using it hevily last days and missing of any information how long should I wait before the job finished making me crazy :) Anyway it is really nice tool.

Dec 13, 2012 Version: 1.03.04 OS: Windows 7 64-bit Ease of use: 9/10 Functionality: 7/10 Value for money: 9/10 Overall: 8/10

yes, I don't know how, but I've missed 64bit version link here - thanks for pointing that!

of course it works now @Win7 64 without a problem.

(only quirk is removing audio channel name - some players might have problem with that)

May 1, 2012 Version: 1,03,03 OS: Windows 7 64-bit Ease of use: 10/10 Functionality: 8/10 Value for money: 10/10 Overall: 9/10

Quick, simple and effective way to downmix all my DTS to AC3.
Those who say this tool doesn't work in Win7 64-bit are mistaken, because it works perfectly for me - it definitely works in Win7 64-bit.
Unfortunately, it seems like the web site for this tool has completely disappeared. Regardless, it still works fantastic.
My only complaints are the usability of the interface (not being able to save output directory options and not being able to set default option for normalizing). Those are minor complaints. The tool is a freeware gem.

ndade7: This program has worked perfectly for me for a long time BUT I have not tried it in Win7 or a 64 bit system..There is a 64 bit program download in here in case you missed it.I have emailed the author a few times in the past and he was very helpful and got back to me very quickly here is his email if you want to write him >>

Mar 19, 2012 Version: 1.03.03 OS: WinXP Ease of use: 10/10 Functionality: 10/10 Value for money: 10/10 Overall: 10/10

Great tool but big drawback - doesn't work in Win7 64bit
(no matter what compatibility setting)

After adding MKV - error "an attempt was made to load a program with an incorrect format
Exception from HRESULT:0x8007000B)"

pity as it replaces a lot of demuxing/converting/muxing jobs
