Burned movie makes popping sounds...

[Kilcher]

Hi everyone.. I have posted a few questions on here and had great responses to them. I have another problem now and need some guidance.

I backed up "Best in Show" and everything went fine and dandy. I used the suggestion to use virtual daemon to trick the computer into thinking that my cue was an actual cd. When I play this "cd" using powerdvd, everything is good as can be.. the sound, the video all perfect.

I then burned the image using the latest version of Nero (copy disc function). While the burning went fine (I first used 8x), I noticed a constant popping sound every 20-30 seconds. It's really really annoying. I thought it was my burning speed, so I reduced it to 4x and the same thing happened. I've been using powerdvd to play the cd not a standalone, so I don't know if this sound will disappear on a dvd player, but I'm guessing it won't.

Has anyone had this problem before? I'm encoding my audio at 128 (with no downsampling conversion).

Thanks everyone!

Just to be sure. Are you using the latest version of DVD2SVCD 1.07.4?


I think I have heard of this once before. If I remember correctly it turned out to be one of two things. Either the player had problems with 48 audio or the bitrate.

I think it's the player that is at fault, sort of. Since the SVCD spec is for 44.1 audio at 224 bitrate, but I have only ever real heard of a problem like this once with out of spec audio. It was some time ago and I trying to remember.

I would suggest trying these things:

1. try using a different method to burn the CDR. There are several very good methods listed in the DVD2SVCD FAQ. Personally I like using VCDEasy and CDRWIN and dislike Nero.
2. Try downsampling to 44.1
3. Try increasing the audio bitrate to at least 160.
4. Lower the overall bitrate of video + audio. My Pioneer player would have problems with audio if the bitrate was too high.

Thanks for your post markrb. I will try to downsample the audio. Is there a point not to do it besides speed? Is quality really that noticable when downsampling to 44.1?

I will also try to use VCDeasy. I love Nero and use it for all my burning needs, but apparently it's not so good for doing vcds.

I will redo them and let you know my results in a few days.

Thanks again!

As for downsampling 99.99% of DVD players don't need it, but there was a post not to long ago that if this person did not downsample he had audio problems. You might be having the same problem.
If the combo of everything I suggested works then 1 by one change things back until you have a problem.

I never would have even suggested downsampling would fix your problem if it wasn't for that post.

Mine needs downsampling.

I have a hitachi dvp 415u and mine does the hiss & popping also.

I leave my audio @ 224 with the 44.1
