The problem is not the result - as I wrote, I think is quite good - but the method... I mean, what kind of deinterlacing method VirtualDub uses as default? And if I want to try another one, how could is possible to record interlaced captured video?

At the end if I decide to make DVDs or AVCHDs, as it is possible to make them interlaced, how could I'll make them interlaced if the captured video is deinterlaced?!?

What I'd like to know: is there any "stupid bob" deinterlacer to use with VirtualDub, that record the captured video as the original material - 720x288 at 50fps - so I could use whatever deinterlacing method - in VirtualDub itself or AviSynth? Or, if I use any kind of deinterlacing filter WHEN I capture the video, the result will be the same?

These are important questions, as I want to capture literally hundred hours of video (using different versions, discs, players) and I must start right... I can't think to redo everything at the end because I captured with wrong settings!

By the way, my capture card is an Asus BDA (based on the Philips SAA713x chipset) and VirtualDub uses it via DirectShow.
