Still very new to this, be gentle with me.
Had 2 audio problems so far.
1st: I converted an AVI to MPEG-1 using TMPGEnc. Didn't fiddle with settings. It converted fine, and on my computer it plays fine. Then I used VCDEasy(latest version) to burn it. Still not fiddling with settings. It seemed to burn just fine. But when I put it in my DVD player(Magnavox MDV410) the audio cuts in and out. Get perfect audio for 4-5 seconds, then nothing for 4-5 seconds. All the way through the video. Won't play at all on my other DVD player(Sony something or other). Oh, and it plays just fine on my computer from the disc in Media Player.
2nd The 2nd file I try, when I convert it the same exact way the resulting MPEG-1 loses audio 8 seconds in. Played on computer only, haven't tried to burn it. No sounds for rest of video.
Both are DivX I think. MPEG Layer-3 audio.
If anyone could tell me what I'm doing wrong that would be wonderful. Preferably in layman's terms so as not to fracture my brittle mind.
I suck.

More worried about the audio issues really. If it plays good on any of my DVD players I'll be happy.

Try using a small prog called Gspot to analyse the avi first,so you know what format the sound is in.
The method i use to create vcd's is this..(and i rarely get any problems)
Use tmpgenc to encode the Video ONLY.
Then use Virtual dub to save the audio,rename the extension(mp3,ac3 etc)(depending what gspot told you)
Then convert this to an mp2 (44.1 khz,224 kbs) finaly put the audio & video back together (using Tmpgenc)
You'll find your sync/audio problems will reduce greatly.
I never have any problems with my Sony DVD player playing vcd's,both cdr's & cdrw's play fine.
Ps if you want a better quality vcd you can up the bitrate from 1150 to what you want (2300 max) but it will increase the file sizes.

If you up the birate it will be non standard and probably play back slowly! Thats why i dont like vcd, step outside the standards and it causes too many problems!! SVCD is just the solution!
VBR SVCD murders VCD completely! Especially that created with CCE SP!
As for the audio troubles here! I have heard of it before, and the solution that time was that this person used 48000hz as the sampling frequency instead of the standard 44100hz and it worked for some bizare reason! My guess was the dvd player just sucked at playing 44100hz lol, there's just nothing else it could be!

You're right about an svcd being a better format...but thats not much good if you're dvd wont play them....like mine.
If you inrcrease the bitrate they play just fine but you have to keep the resolutions 'standard'
(352x240 ntsc & film,352x288 pal)

hi, guys. here's the newbie again. Thx for the last encoding help Dela, it worked.Tmpgenc is much better then Nero for the encoding bit. BUT.... yes, audio probs here too. I used Tmpgenc 1.5.3 to encode an avi2vcd. Picture was fine but no audio. I started switching the bitrates (no effect), tried different audio-formats (no effect). Even used the tmpgenc online manual step by step with altering (chronologicly) every setting wich could effect the audio output. No effect whatsoever.
The avi-file did sound strange when played (almost mono) and was called "<Title>-postX.avi"
Any help is very welcome.

open the avi file in cirtualdub and do the following
1. click video - direct stream copy
2. click audio - full processing mode
3. click audio - compression, select no compression pcm and click ok!
4. click file - save as avi!
use the avi saved with TMPGEnc

Thx dela, it worked.
The audio came back. I think it was caused by a bad rip.

Puts mpeg-1 non standard video cd headers on an mpeg-2 SVCD file to trick a dvd player into playing it!

Speaking of audio problems, I have used TMPGEnc to convert to VCD on a variety of AVI files (about 1.5 hr long). A small portion of them lose the audio quality after 35 min to 60 min. At that point, the audio drops on and out. But the first 35-60 mins are fine. Any ideas? Note that I have not been able to open any AVIs with VirtualDub.

First make a codec check and then click option - environmental setting and click the vfapi plug-in tab, right click directshow multimedia filereader and click higher priority until the priority is 2 and at the top of the list!

Hello, Dela,
I changed the Directshow Multimedia File Reader parameter a long time ago (it was probably one of your suggestions) to '2', top of list. I needed to do this since I wasn't able to open any AVIs until I did so.
When you say 'codec check' I must assume you're referring to the status window at the bottom of TMPGEnc screen? It says: Video-CD NTSC (MPEG-1 352x240 29.97fps CBR 1150kbps, Layer-2 44100Hz 224kbps). If I run GSpot on a good file and a bad file, the output appears the same. Note again that the audio problem can take an hour before it shows up.
Anyway, many thanks for the reply.

Are you converting to 29fps say from 23.976 (most downloaded films are 23.976) ?

You are correct .. in fact, TMPGEnc pre-completes all the settings and greys-out the edit boxes. Would you be suggesting that I edit these values (not sure if that's possible on greyed-out fields tho)?

Well you can use the project wizard by clicking file - project wizard and use a VCD option or if you want to manually edit it, click load and go to the template folder in TMPGEnc and then the EXTRA folder and load unlock.mcf.

Thank you, Dela and Acheron. With your guidance I was able to finish one of my 'problem' projects. I anticipate success with the rest of them. Thanks again for your patience as well as sharing your knowledge.
