Problem with Audio

[HEB1022]

I am having an issue with a section of audio on a DVD. The specific section has music over still images. All other portions of the audio sound good. It sounds like the music is cutting in and out, very jerky. The video looks good during this seciton of video. This sound anomoly is not happening when I play the redenered output on the computer, only on the standalone DVD Player.

Anyone with any advice on what to try, would be appreciated.

Thanks in Advance,

My software:
Original Video Editing - Sonic Foundry Vegas Video 4.0
MPEG Rendering - TMPGENC 3.0 Xpress
DVD Autoring - TMPGENC DVD Author 1.6

The parameters uses for Rendering were CBR 9bit interlaced, Audio MPEG-1 Audio Layer II, 192kbits/sec, Total bit rate 9200 (video) + 192 (audio) = 9560.

I can only suggest reburning, perhaps to different media. Everything else looks sound to me.

I was burnign with VBR before, and got some pixelation that I was trying to fix by going with CBR. The video seems fine now, and 99% of the audio seems fine..only when the video is still frame (no motion) does the sound start breaking up. It makes me wonder if the bit rate during this section is droppign below some value that makes the dvr player hickup...make any sense?

If you are going CBR, then the bitrate should not drop. If you are going VBR, the bitrate should not fall below the minimum value, or rise above the maximum value set by you. That is in an ideal world. Some encoders do creep above the limits you set, but rarely would they go high enough or low enough to cause problems unless you force them. You can check the bitrate by turning on the information display in PowerDVD, or the on screen display on your standalone.

That was a good suggestion. I played the dvd with the on screen bit rate display. During the bad video, the overall bit rate would "bounce" between 7500 and 10000. This would happen anytime the picture on the screen was a still image. Whenever the picture had any form of movement, the bit rate seemed more steady between 9000 and 10000. I think this is key to the problem, but I don't know how to get TMPGENC to keep the bit rate constant during "still images"..any ideas very much appreciated.

Thanks,
