i take it you mean movie trailers or video of some sort not programs as in software yeah?
if your graphics card has an svideo tv out socket (round 4 or 7 pin connector click here ) then all you need to do is get hold of an svideo to composite adapter (should have come with your graphics card and looks like click here ) and run this to your tv. enable clone mode on you graphics card and then any full screen video or game you play will also be shown on the tv set. set your vcr to the tvs av channel and record it.
or run the lead to the video directly and select the av channel on it.
