know nothing about free converting programs.. i guess you can try to search for some screen capturers. as for real converters i can advise you to visit http://geovid.com
i use their video to flash converter. can convert from any video format (depends on codecs installed on your system) to swf or flv. also can add logos/watermarks, generate html code for your website... what else?.. has some video effects. well i like that tool :) and i use a free trial version, it has no time limitation and it's full.
