ATTN Haig and others: Got rid of my DVD stuttering by...

[Gavin]

unchecking the "Use LFE decoding" in
DVDGenie's More Options...

Now there's no more stuttering when
using DVDMax, I can copy my DVDs to
VHS now, using my Macrovision descrambler.

Hi Gavin,

This is one of those things which makes no sense to me.

LFE decoding (low-frequency effects)is the part in the audio stream that is sent to your subwoofer.

When you see specs like 5.1 or 7.1 or 8.1, the ".1" is the subwoofer (LFE)channel.

The AC3 signal goes into a decoder, then into a downmixer, into a 2 channel D/A converter and then out to a stereo output.

Or,

AC3 signal goes into a decoder, then goes into a x.1 channel D/A converter and then out to your sub and surround speakers.

Just curious are you still getting the same quality of audio out of your sub with this off?

If yes, then you really confused me

I've got it. The bass from the subwoofer shook up his system and made a good electrical contact possible.

I don't see any sense in it myself

I just disabled it (didn't change anything
else) and, lo and behold, no stuttering
anymore on my tv...

Maybe LFE-decoding took some precious
processor time, maybe the people at
Ravisent/Cinemaster introduced some
nice little bug into their latest
engine (I updated to 2.0.36.6145 in
order to be able to watch 'The Matrix'
with its special features enabled),
I honestly don't know...

I'm one happy MURCer now

BTW, although I have a Dolby-Surround
Set, my neighbours wouldn't like a
subwoofer . There also remains a
lot of bass (the shooting scene in
'The Matrix' for example) with LFE
disabled.

You cannot imagine how happy I was
after I discovered this

Well, if you actually do not have an SPDIF card in your system, and listen to the audio in Dolby Surround mode, there is absolutely no sense in enabling the LFE encoding anyway, as you do not have a card that would output a separate suboofer channel anyway.

Maybe the cinemaster is stuttering because it does not know where to put the nice sub-woofer signal...

hi
i have it unchecked to begin with and still a judder?
could you tell me what your dvd genie version is
mines 3.20
and what your other settings are please?
thank you
CMB
i hope it will work for me too

[Haig]

I'll send this off to Ravisent and see what they make of it.

Meek - If LFE is enabled and you don't have a SPDIF out, then the downmixer is supposed to mix the entire chain of audio signals into a stereo out. Could be that there is a problem in the downmixer section.
