Which VirtualDub version is best for capturing analogue signal to digital lossless ( HuffYUV, PAL, 720 x 576, ATI AIW USB and so on - best settings for example not interfering with capture, making them trouble-free, etc.) ?
For example, there is a version with pre-loaded filters for work after capturing of the signal - editing(so probably called: version LordSmurf). Perhaps, for example, these filters, even though they are not enabled, somehow burden VirtualDub and capture ?
Does it all matter?

Use VirtualDub 1.9.1.1 32-bit (lordsmurf's download, which you mentioned).
Do not use VirtualDub filters during capture. Not ever. VirtualDub hooks into your capture device's software and can link you to its proc amp settings. The only adjustments you should use during capture are Brightness and Contrast. They are used for setting input black levels and white levels and can be checked with VDub's capture histogram. Filtering, denoising, color, etc., are processed after capture. Always.
VirtualDub capture settings are explained in great detail in this guide: http://www.digitalfaq.com/forum/vide...-settings.html.

I thought the best solution is to leave the "colors" setting (generally speaking) on the default values - without changing them.
Among other things, that VirtualDub capturing on the fly under its own conditions without processing other data set to it (maybe it is easier - on the default ones) I mean "colors" and filters are off, etc.

VirtualDub < the one linked here.
Never use the VirtualDub "levels". Instead alter brightness/contrast in the crossbar controls.
That's the card proc amp.
Noting still not as good as external analog domain proc amp when needed, like SignVideo/Studio1 or DataVideo.

With most capture devices, the proc amp dialogs that appear under "Levels..." ( VirtualDub Capture settings guide, post #4) and in the "Video proc amp" tab of the "Capture filters..." dialog (video decoder tab, VirtualDub Capture settings guide, post #3) are exactly the same. As with a few other settings, the proc amp controls can be accessed through more than one dialog.
Adjusting colors ("Hue") is a far too simple operation in YUV and is usually a futile exercise with analog tapes, which change color balance with every scene. It's worth the effort only if the same color balance problem exists consistently thru the entire video. There are far more sophisticated post-capture color controls in Avisynth, VirtualDub, and many editors. "Brightness" and "Contrast" don't affect color but are used to manage overall input signal levels and are measured with the capture histogram ( VirtualDub Capture settings guide, post #3).

Do you mean those settings in VirtualDub about which sanlyn writes: brightness/contrast ?
Thank you for your help so far.
