The response to my post last week about how to convert digital photo collections to DVD slide shows was a resounding, "Whatever. How can I grab a screenshot from a video or DVD?"
Who knew that the number of would-be "screencappers" was so legion? Regardless, I'm your humble servant, and your wish is generally my command.
First off, for image screen captures of digital video files, I highly recommend VLC Media Player. I know I mention the free media player quite a bit, but it's still the cream of the freeware video crop for me due to its light footprint and flexibility.
