Hello,
Since I am running my new computer with my old Terratec G3 Premium and the new Virtualdub 1.10.4 I got really fast really bad clipping-issues with one of my vcrs. On the other hand, the older vcr works totally fine, with the exact same settings and source materials. I turned the volume meter on and saw a difference too, the new one is way too "loud" and pushing the bars directely up to 0 db in almost every peak of the source material. the old vcr is way more "quiet" and produces no clipping whatsoever.
I tried experimenting with the lower audio levels in the capturing settings of the G3 but it seems to do nothing at all. The issue semms kinda weired too, since it only happens with my new vcr AND my new computer. I tried my old laptop and had no problems with both of them. That leads me to the point that the issue is somewhere located in the settings of my new computer but since the are not too many options in the audio section I'm somewhat clueless.
Maybe I'm just too blind too see a solution, at least I'm hoping so - I'm glad for any help  |

I would also appreciate any kind of suggestions in the audio-section - anything that might work is fine too |

I guess nobody knows? I've never done analog capture with VirtualDub, so I'm not much help, but I'll throw out a couple of thoughts.
Re: volume not responsive, I suspect a hardware-specific setting. Note, some VCRs have two sets of outputs, one controlled by the volume setting, one not.
As a brute force workaround, try recording your audio separately with Audacity.

Well, I'm kinda a step further now: The lower pitch does reducing the audio-level, I just have to turn it really low, between 1 and 4. But that doesn't solve the issues with sources that are either way too loud to beginn with or have nasty peaks, which cause again clipping.
I have checked some older videos I have made with my old computer and "old" virtualdub 1.9 and saw something very confusing: a lot of videos i have made so far have these kind of peaks, it is clearly visible in the audio display. but there is no clipping to be heard.
That leads me to the question if virtualdub is doing some kind of audio-limiting and cuts of "illegal" frequencies at 0 db or not. Maybe something changed between version 1.9. and 1.10., I don't know. Maybe my internal sound card needs a little bit more resources to work with... I'm kind clueless, maybe there is someone who have some ideas, because recording audio and video seperately is no option 
Edit: Maybe clipping is not the right word. but there are some "pops and clicks" to be heard whenever the volume goes to hight. |

I can not immediatly check this out myself via my USB video/audio recording device, but maybe the following information may help...
In Windows 7, via the Start-button > Control Panel > ( click Small icons instead of Category) > Sound, you have a window with four tabs.
One of them is "Recording". You will see an External Mic, an Integrated Microphone Array, and a Stereo Mix.
At the Stereo Mix there should be a green check mark, meaning that it is active.
At my opinion, this Stereo Mix handles the sound that comes in from your Terratec device, via the USB-port.
When you do a right mouse-click onto this icon, and then click onto "Properties", you will have a window with "Stereo mix properties", and you will see four tabs in it.
One of them is "Levels". At my computer it is at 100. Maybe at yours it may help by lowering it down ?
Besides that, you will probably also find, in the "Control Panel", a specific icon for the soundcard in your computer (mine is IDT Audio).
When clicking on that, there is a window with a Playback, Recording and Preferences tab. In the Recording tab it is again possible to set the volume for the Stereo Mix. At my computer, at verifying this, it is bound to the Stereo Mix level-setting via the "Sound" icon in Control Panel. So, I can choose between the two of them.
Regards.

And make sure you get the right hole...
