I have been away from making VCD's for a while now. This is all due to a synch problem I am having. This problem only occurs to mpegs not avi's. Any source file I Download or create myself plays back with the audio 1-2 seconds later than the video. I removed all of my drivers and codecs to try to resolve the issue. I even upgraded my Win 98 to Win 2000 hoping that a new core OS would fix this issue. I am trying not to have to reload completely and I AM hoping this is common and there is a fix. CAN ANYONE HELP? This is driving me nuts!

Thanks, Sam

I am not sure if it would help you or not! I also had synchronization problem and my audio lagged the video by 0.5-1 seconds. I used TMPGEnc to demultiplex (seperate the audio and video). Then I cut the initial 0.5-1 seconds of the audio. After that I multiplexed them again. It worked fine for me. My files were not that big and my PC is very fast. So it didnot take much time. Hope it helps

I'm not going to be much help, but I had a similar problem. An AVI file I would create would playback fine, but when I converted it to MPG (using TMPGen or Ulead or some others) the audio would start 250 ms slow and get steadily worse. It did it no matter what codec, size audio setting or whatever I used. Oddly enough, I found a free program (AVI2VCD or something like that) that would convert it without the bad audio sync, but it did a terrible job on the video conversion and was unusable.

On my Windows ME system, I never could get it to work, but I installed the same card (ATI TV Wonder) and software onto my 2nd machine, a very similar system except running Win98, It worked fine. No audio sync problems at all. I fought it for weeks on the ME system. Downloaded ATIs new drivers, tried codecs, changed settings on the system (hardware acceleration, etc.) and nothing made any difference. The 98 system worked first time.

I don't know. Good luck. Stuff like this is why I like to keep at least two computers in these days of buggy operating systems... Doubles your chances of something actually working!

I'm fighting the same issue with my ATI All in Wonder on a AMD 1700 running Windows 2000. I had the problem for a while, fixed and it worked fine for about two or three weeks then the audio went out of synch again. Of course I didn't write down what I did and can't remember for the life of me what I did. I am revisiting all the sites again in hopes of stumbling on the resolution again.

I know it had to do with unistalling and reinstalling either a software package or a driver, I just can't remember which one.

I am responding to this site to add addtional testing methods to determine if it is truely a out of synch file or the system. If you are havin the problem on one or many mgep files, then play the file in Quicktime Player (I am on Version 6). If the file plays fine then it is not the mpeg it is the system. If the file is out of synch or goes out of synch about half way through then it is the file.

I have been researching the difference in Quicktime vs ATI Player, Media Player and Real Player, but haven't found out a whole lot yet. The only problem with Quicktime player is it doesn't have a fullscreen mode, if it did then I'd assume it would either have the same problem or I would use it for the time being and keep researching the issue when newer drivers were released.

Well anyway I'll try and make it back to this site and others once I remember how I fixed it the first time.

Thanks

I have a similar problem, but its just a file i have slowly gets out of synch. is there any program or method i can use to somehow watch the movie without it gradually de-synching??

If you are seeing a progressing loss of audio synch, it is probaly NOTHING to do with your drivers, versions or all the usual crap you will read about in forums. Chances are you have an NTSC source and have tols the VCD it is PAL format or vice versa. Since NTSC is 29+ frames a sec and PAL is 25 frames a sec, you will find your audio failing to keep up cause it is synched according to frame number. Make sure when you burn a VCD (in Nero for example) that you Tell the program your video formate is the SAME as the format of the video part of the MPEG stream! Hope this helps - seems there are lots of people reinstalling their programs and machines cause they dont understand this simple issue - and sadly forum experts are good with weird versionning problems and IT related issues but often miss the video basics...

Well I'm sure the above answers could sort some people's problem but this is what solved it for me.... I was starting with a mpg that was in synch that grew progressively out of synch by about 2 seca at the end of a 40min mpg. I tried all of the above to no avail. Finally i created a new wav. file using Vitualdub and input this as the sound file to Tmpgenc and used the original avi file as the video input... hey presto using the NTSC DVD format in Tmpgenc produced an insynch mpg that DVDWS had no problems with...hope that helps...
