SVCD to DVD-R Problem(using dvdlab)

[neo_tech]

Hi everyone,
i had 2 movies in the svcd format which i wanted to burn on a single dvdr. i followed this very nice and easy to follow tutorial(https://www.videohelp.com/guides?link=727) written by reboot. i burned it and it played nicely on my standalone. only problem am now facing is that sometimes when i pause the movies on y standalone and then resume it, theres serious audio/video sync problem. like audio comes first and say after 2 secs. follows its video :/ .this happens only some times not always.
can someone pls guide me how to avoid this problem

PS:i followed that tutorial line by line.

Thanks

Buy a better player
Don't use SVCD source

That's pretty much it. SVCD is not DVD compliant, so not all player will play it correctly when authored this way.

buying another player is not an option for me as i bought this last month. the players performance is simple outstanding. so far it has been able to play 99% of the formats including xvids,divx, and many custom type formats.

i just want to know is there something which can be done to avoid this sync problem?

one more thing i would like to ask. am new to all this burning thing for standalone so let me ask some newbie ques.

1st) an svcd can be easily burned on cdr/rw and played on standalones, then why can't it be simply burnt on the dvdr/rws? i mean whats the reason? is it the chemical on the dvd discs that the players detect and hence expect a dvd-video input or something else? i mean how r the standalones concernced on what media it is being burned, be it a cd or a dvd(where both r supported)

2nd) can a dvd-video(those with vob and ifo files) of small size(within 800mbs) be burned on a cdr/rw and be played easily on standalones? or will there be a problem?

thanks

1. Don't know why, but similarly you cannot burn a VCD to DVD disc as a VCD. It is something to so with the file system being used, I suspect.

2. Yes, you can burn a small DVD structure to a CD. It is called a mini-DVD. It is playable in very few players, and you have to keep the bitrate down as well.

I still think your sync problems are not authoring related, but down to your player.

However, as a test, try burning just the mpeg files to a data DVD, instead of authoring, and play them back that way. See if they have the same issues. If then do, try authoring again, but this time demux and let DLP remux when it authors (if you didn't the first time)

what the...thats unfair u can't burn a vcd onto a dvd disk but u can burn a dvd onto a normal cd. discrimination! lol...

can someone here pls explain me WHY does the standalone need to bother about the disk type when it is being provided with a compatible and perfectly authored dvd svcd or vcd. why we can't simply burn svcds on dvd. like why doesn't nero has inside the DVD burn enu a DVD-SVCD option just like it has under the CD burn section.

btw i used the demuxing(highly recommended thing) option. i think i'll have to live with it. btw whats DLP remux(with its full-form pls) ?

I still think your sync problems are not authoring related, but down to your player.

I agree. Try pressing the reverse button on your remote control to go backwards on the DVD and then play it normally and see if it is in sync. Sometimes this works on my cheap DVD player when Divx files are out of sync.

guns1inger means that instead of giving DVD Lab Pro complete SVCD files that have both audio and video in the same file that you should demux your SVCDs into a separate audio and video file for each SVCD and use these separate files in DVD Lab Pro as it will mux them itself into the completed DVD.

jman98 i just had that out-of-sync problem again and i reversed it a little and played it again and BINGO! it worked. back in sync again

oh ic. so it means that the demuxing which dvdlabs recommends highly in the very beginning is different from this one. i should provide it with separate the audio and video files. can i use Tmpgenc's MPEG TOOLS for this purpose? if yes then should i use simple de-multipplex or normal demultiplex? can u also pls tell me the difference between the 2?

thnx

[jman98]

It's been a very long time since I used TMPGenc to demultiplex. I now use MPEGVCR (a video editor) if I need to do that. I don't think there's any real difference between the 2 kinds of demultiplex and I don't know why they have 2 instead of just 1, but I'd say for you to use the normal demultiplex and you should be OK.

Glad that the suggestion to reverse worked for you. That's an easy fix. Since this worked, probably your DVDs are OK and it's just a problem with your player. You can try the demultiplex step and see if it helps.

The difference in simple demultiplex and demultiplex in TMPG is that simple demultiplex will demux automatically video and audio (and if you have more than one audio track it will demux only the first one) while in demultiplex you can choose which track you want to save to a file.

thanks you abond and jman98 for clearing out my doubts so nicely.

thanks to all.
