Hi,

I'm using a Leadtek Winfast 2000 XP capture card (BT8x8 Chipset) for capturing video via S-Video.

The software that came with the card, "Winfast PVR" is easy enough to use, but all of my rips are coming out with frames like the one below.

It looks a field de-interlace has been done? This happens if I rip to MPEG2 or to HuffYUV.

Can I use another software to get around this de-interlacing and do some kind of better deinterlace?

What would you recommend?

Try Virtual VCR (http://virtualvcr.sourceforge.net/) or iuVCR (http://www.iulabs.com/iuvcr/index.shtml). For deinterlacing your captured video I recommend AVISynth (http://www.avisynth.org/) to create an AVISynth script to apply a deinterlacing filter such as TomsMoComp (http://www.trbarry.com/downloads.htm) or Decomb (http://neuron2.net/decomb/decombnew.html).

the MyHD card does this as well (in analog mode). very annoying since i can't bypass with current drivers. anyway, i still use virtualvcr with an older bt8x8 for analog sources. you should probably install the latest btwincap drivers as well.

I believe that Winfast is set to this de-interlace filter being active
whenever you start up the PVR app. I think you can re-set it inside the
registry though.

But, VirtualVCR and iuVCR both do not have this issue.

Note, that virtualVCR does not segment its captures, but iuVCR does !!
And, virtualVCR locks it's video fps (ie, 29.970) while iuVCR does not :( !!
unless I'm missing something here.

My card is the Winfast TV2000 XP "Expert" - REV C make.

Thanks for the help !

I've been using VirtualVCR, and de-interlacing with TomsMoComp via AVISynth later.

I had a look at iuVCR also, but I prefer VirtualVCR as I don't need segmented capturing.
