Video/Imaging Softare Recommendations?

[RedMonkey]

Can anyone recommend automated software that will capture image frames from video on a windows machine not Macs. I used to use virtual dub but for some reason I keep getting a "sync error" not really sure why. Of course all the while keeping pic clarity pref. even after I enlarge them. Thanks in advance!!
