Syncing problem?

[Falcon500]

I have a muxed Mpeg1 NTSC file with the standard MP2 224kbit and 44000Hz audio that I want to convert the audio to the same MP2 224kbit but with a 48000hz frequency. I want to author a DVD with toast using these Mpeg1 files (not converting them to Mpeg2). If I set toast to do the task it converts the files (or at least alters the audio from 44KHz to 48KHz) but the sync is out.

I have tried the passthrough video and set the audio frequency change to 48000hz in ffmpeg but I also get the same syncing problems with the resulting Mpeg1 muxed files?

I'm not sure about which process exactly you're following. You can also consider the S/VCD>DVD tool if you use the registered version.

This is the process I have selected below. I don't think the SVCD->DVD trick will work as the original file is not Mpeg2 (480x480) SVCD format it is standard VCD format. As you can see from the process that I am just passing through the video so it will be muxed at the end. It is only the frequency of the audio that I am changing.....

I don't think the SVCD->DVD trick will work as the original file is not Mpeg2 (480x480) SVCD format it is standard VCD format.

The S/VCD>DVD tool will accept both SVCD and VCD as input. Otherwise try to convert audio only and remux video and audio.

Sorry I miss understood how the SVCD ->DVD tool worked. I have tried just encoding the audio and then remuxing with the video but it is still out.

How does the S/VCD->DVD tool work? Does it convert the Video to Mpeg2 ?

I haven't got the full version of ffmpeg to try this feature.

How does the S/VCD->DVD tool work?

It automatizes the demuxing, audio resampling, remuxing, and reauthoring of any number of MPEG files, VCD or SVCD files located inside a folder. The video stream is not re-encoded.
