Need help with Virtual Dub please.

[Sulaco]

I am using Studio 8 to capture and then opening the AVI with Virtual Dub to create either a filtered AVI or an MPEG-1 file (depending on what I am doing) and no matter what I do, I lose the sound. I leave the sound settings on default (AVI sound) and am using tooLame as an external encoder. Can someone tell me what to do to get sound back? I don't want a seperate sound file (WAV or MP3), I just want the sound to encode with the video.

You may HAVE to seperate the audio (ie:extract audio as WAV and use as audio source during encode using TMPGE).

If you're using Toolame as an external mpeg audio encoder, then you are N*O*T using the default settings for TMPGenc.
Try a plain vanilla default setting with TMPGEnc. You can do this by clicking on NEW PROJECT -- Tmpgenc will ask DO YOU WANT TO RESET PROJECT? then answer YES . Then simply click on the Project Wizard option and choose VCD NTSC template from the Wizard. At that point, all the options under VCD NTSC will be reset to plain vanilla with nothing but standard settings selected.
Probably what is happening is that you have got some settings checked somewhere in the guts of TMPGEnc which are incompatible with some other settings. One of the slight disadvantages of TMPGEnc is that it has so many optional settings and controls that it's possible to choose an option which directly conflicts with another option. (One example of this is the fact that you can choose the SVCD template but then choose MPEG-2 instead of MPEG-2 SVCD as the STREAM TYPE. These 2 settings conflict with each other and produce an encoded MPEG-2 stream doesn't play correctly.)
Very clearly you are NOT using default settings if you have chosen the AUDIO option in MORE SETTINGS and then drilled down into AUDIO to turn the EXTERNAL ENCODER option on. None of those settings get turned on in a completely fresh start-from-zero default VCD NTSC template.
"Default setting" means you don't click on anything optional or unusual. This means that NO options in the Project Wizard screen 3 of 5 menu (specifically NOTHING from the OTHER SETTINGS radio button) should be turned on and NO options in the Project Wizard should be clicked to turn them on other than the simple VCD NTSC template option in the Proejct Wizard. Try encoding a VCD with completely plain vanilla default VCD NTSC settings with absolutely nothing else switched on or modified. If you still get a VCD with no sound, the problem lies elsewhere than with TMPGenc.

Thanks for the replies guys. I guess I should have been more clear with my post. I use default settings and experience the no sound problem and I also use the tooLame codec and experience the same problems. I guess, from what you are saying xed, that maybe the problem is not with TMPGEnc and is in the source file. I will try something else. Thanks again.
