i have just had a film in that when i play in my standalone dvd player the video is fine but the audio is like a gurgled screech.

when i put it in my pc dvd it plays and sounds fine.
the audio is showing up as pcm in the power dvd window does anyone know how to sort it so i can play it on my standalone

any help appreciated

LPCM is the most "standard" audio format there is when it comes to Video DVD. Are you sure it's in the correct format? (48 kHz)

obviously its something to do with the audio format being in pcm
could anyone tell me if this can be converted into mpeg 1 or 2 format

also what is pcm audio sorry but this is the first time ive come acroos this

[mats.hogberg]

PCM is WAV (kind of) uncopmressed audio. Yes, it can be demultiplexed and encoded to AC3 and/or mp2 and reauthored (and multiplexed with original video m2v) again. (Depending on your authoring software).

[disturbed1]

Change the PCM output settings under the audio menu on your set top DVD player. This is usually in the system settings.

Most people just get no sound or soft sound when LPCM is used.

mats is there a guide on how to demultiplex it and turn it into ac3 then remultiplexed

and thanks a lot guys you are stars

[mats.hogberg]

Use ReJig to demultiplex VOB(s) to m2v and LPCM
Use ffmpeggui to encode to AC3
Use IfoEdit to author (and multiplex) back to VOB/DVD

i demuxed the vob files so it gave me the pmc audio file but when i try and load it into ffmpeggui it doesnt show as a valid audio file

any ideas what i done wrong

[Nelson37]

Not sure if this is your problem but I'm fairly sure that 352x288 is DVD-compliant only in MPEG-1, not MPEG-2.

[karateman6913]

cant see what thats got to do with the audio m8

anyway it looks like the way this film has been burned is from an svcd to dvdr but my standalone wont play svcd sound.

so how can i get round it

it plays and sounds fine on my pc dvd player and i have tried the pcm channel under audio on my standalone menu but to no avail.

[mats.hogberg]

Can you load the demuxed audio using some audio editor like GoldWave, then save as wav, then ffmpeg it to AC3? If not, there must be something seriously wrong with the audio...

[karateman6913]

lets see if i am demuxing right first

dvd in drive
open rejig
file mode
add then load the first vob file up which then automatically loads the other remaining vobs
these load up in the job side on left
on the right stream list and demuxing we have 2 files

mpeg
lpcm

set output file leave box ticked in 1 pass

click demux

is that right so far

[mats.hogberg]

...erh, if the DVD is not CSS encrypted, yes, but I'd suggest ripping it to HDD first with DVDDecrypter or similar.
