Video for windows (VFW) may be accessed from two drivers:-
1. Traditional (for viewing) This driver delivers good picture quality but has problems while doing capture.
2. New (for capture) :- This driver is primarily for capture. capture is smooth and I have captured hours of tv program using this.
Notice the difference between the dialog boxes for choosing the various options, like say the video source etc between these two drivers.
The video for windows vfw drivers can be changed from the WinVDR options menu.
For viewing the video, you can use either the preview or overlay option. The overlay option uses much less CPU than the preview. So, overlay is the better choice.
