No sound DVD when playing with certain media player programs.

Here's the problem. I have many dvd's made over the last few years from digital 8 camcorder. I have used a few different programs to edit and burn them to dvd, windows movie maker, nero, and roxio are a few.

I have had a few of my first discs start acting up, they weren't on quality media, so I started to back up my burned dvds to a large hard drive I purchased. After doing about 8 -9, I was checking a few of them and noticed that some of the backup files, when playing through Windows media player or Interactual dvd, both most recently updated, have perfect video, but no audio. Checked all my audio settings and they are okay. I tried playing the burned dvd's and got the same, no audio.

I took a few of the discs and played them on my settop player and they play fine with audio. I played one of the faulty discs with the Intervideo Xpack Mini DVD player and it plays with audio. I know this disc was created with roxio. Just for the heck of it, i tried removing the audio folder and still no audio in the previously mentioned players. I also renamed some of the suspect VOB backup files, changing them to MPEG, and they play, choppily, but with audio.

So, my question is, what can I do to make a backup that actually captures the audio from these discs? Any particular of the many backup programs that might work the best. I believe I used either roxio or dvd fab decrypter to make the backups.

The audio is probably there but your computer players probably lack AC-3 decoders or MPeg codecs that usually cost extra because of licensing fees that someone must pay. All hardware DVD players must have MPeg and AC-3 licensed playback. It is built into the cost of the player.

The software that came with your DVD writer usually includes licensed players.

If you want audio that will play back on anything, keep the native LPCM next time you transfer from your D8. Just spec LPCM audio when you author the DVD.

Thanks for the response, but I know the audio is there, as stated when I play the backups back using Intervideo Xpack mini player, I get the audio, so my computer is capable of reading the audio. I'm trying to find out if anyone has an idea as to how to go about getting a backup made that recognizes the audio.

The audio is there. If you want it to play on anything convert it to uncompressed or something like MPEG-1 Layer2 (like a VCD).
