I've just had installed a dual camera dashcam in my car and I'm very please with how it performs (Street Guardian SG 9663 DC). The camera has a parking mode of the pre-set/adjustable frame-rate type. I've set mine to 1 frame a second, although there are a couple of higher frame-rates available. When watching parking-mode video it's like watching a very fast Benny Hill clip (if you're old enough to remember him !). If I should ever need to recover information from parking mode video, e.g. a car reg. number, I want to slow the replay down to a manageable viewing speed. It has been suggested to me that VLC would be a simple option as you only have to operate the left and right arrow keys on the computer keyboard to adjust replay speed. However...... when I tried to download VLC to my computer my Norton anti virus software prevented the download with a dramatic 'end of the world' warning message ! I did a quick Google check on VLC safety and found conflicting information. Apart from only downloading from the originator's site (www.videolan.org) it seems there is a security loophole in the software. Have any forum readers experienced problems using VLC on their computer, or used another easily manageable viewing programme ? Any advice greatly appreciated, thank you.
