I will see if I can find the original version of VirtualDub and try it and report back. Its just a rebranded Conexant Polaris Video Capture and you can find more up to date drivers for that one tbh. 'How to convert VHS videotape to 60p digital video (NTSC)' and it makes the quality equal to original VCR recordings. I found out about this program for this YouTube video. I need VirtualDub2 because I'm converting VCR tapes to digital. the capture device works with EzGrabber software But quality is horrible from lack of codec's and works with VLC but in VLC I get only sound in the preview and no video but it does capture the video fine.

so it seems that the Direct show has an issue but no setting I can find fixes that. You will probably have to reselect the input source again to get the 'Apply' tab enabled, but once you click on OK you will get audio in all it's glory. When I connect to device '0 Microsoft WMD Image capture (win23) (VFW) ' it works in preview and capture but under 'video' tab I get source and format and in source 'select a video device:' I can select 'Conexant Polaris Video Capture' but no ' video source' or 'capture pin ' or capture filter' or 'crossbar' are grayed out and I cant get to there menu's but if I select device '1 Conexant Polaris video capture (DirectShow)' I get ' video source' or 'capture pin ' or capture filter' or 'crossbar' and their menu's but i get a black preview screen and it always 'fails to start capture'. The way to solve this is to go into the Conexant Polaris capture properties in OBS, click on 'Configure Crossbar' then tick 'Link Related Streams'.
