I've imported 600 VOB's and have always been able to tweak the video sound slider.

Now all my VOB's come in with the slider stuck on zero sound instead of somewhere in the middle of the sound range. I can import and adjust sound OK on the other 2 tracks.

I've had various sound sliders stick before but have always been able to dislodge them by opening/closing the mixer or clicking around on the timeline.

You can see a normal sound graph running across the video track but you can't hear it when played and you can't adjust it off from zero in the mixer. The VOB's play sound OK when launched separately.

Thanks In Advance
