Looks like with an interlaced signal you only get half the lines, and
one field (half field) is just gone. Either that or each field
overwrites all lines instead of alternate lines.

Please DON'T send multiple images this size out again. This list has
1000's of subscribers and your email goes to them all. The web is a
wonderfull thing, post a URL next time.

Cheers,Angus.
