The filter merit choices are broken (for me) in version 2.3a, so I've had to go back to version 2.2a.

What a class release, What a perfection! - perfect 7.1 (8) channels surround sound decoder, and it's FREE plus Open Source!
I LuV this Developer.

Recently I was fixing my buddy's Windows system and came to know about features in this latest release. We literally started dancing when we blasted 8 channel video.

I would like to consider this release either as a Mile Stone or a Hammer Blow b'coz "The World" of Encoders and Rippers is yet not ready for 7.1 channels
Surround Sound. I am still fumbling for audio and video sync even in tuking two channels stereo. Here this decoder is 8 channels ready. Grrrrrrr!

However few things about this release...
1) Sensitivity of LFE channel in Mixer Level Bar indicator seems little bit higher than other channels, or it may be my buddy's system residual noise.
2) It would be great if Mixer Input and Output indicator Bars are provided a separate tab (page) with half-half, so sensitivity and size of bars can be higher. At present tabs are Mixer, Gain, but Mixer, Level, Gain would be better, I guess.

We already started enjoying this decoder up to maximum capacity.
Bunch of Thanks!
:)

It requires 5.1 channel sound card to play 5.1 (6ch) surround sound.
Otherwise set media players in stereo (2ch downmix) mode.

If any one wanna test correct hook-up of surround sound speakers. Download following DD5.1 AC3 Test file

(I can appreciate if above file can be hosted on VideoHelp itself in a misc.tools section.)

I had this problem of volume way too low on my DVD playback. Finally, found the cure ! I'll make sure the word gets out !

PS Only problem is with the loads of functionnality that you can adjust for people who do not know much about it ;)
