Some time ago I took a recommendation from Gizmo Richards' website for a screen grabber from Gadwin.
This has always worked well with me and I've passed the recommendation on to others.
This evening I wanted to grab an close up of an item on a woodturning DVD viewed on VLC - paused the run and inch it to get the frame I wanted, ran Gadwin and it showed the extracted picture, but when saved and viewed in a viewer, it was just blank, and going back to the folder, the .jpg file is only 8k instead of the 100k or so of all other captures.
Any ideas why ? Is this something to do with VLC ? I had to fall back on taking a photo and adjusting it a bit.
