If you want 1 Hour Playing video then you need 324 000 little video bricks
because you can firerelay after 30 secounds to the next brick.
Not really, if you have a 100 event limit on a brick, you could just toggle the events 3 times. I think your maths is wrong though.
If a brick can play up to 30 seconds, thats two bricks per minute. Making it 120 bricks for an hour. Go back to school. :u
