I do agree with you on both points, and had I seen your reply before I made this post may have replied slightly differently. If you have time, take a look at that one and let me know your thoughts - I'm mainly interested in how it may be possible to store a composite video frame in a digital format such that the individual composite elements could be broken back out again.
