Hey ya'll - I was ecstatic to finally join the House of MAC with a spanking new white Leopard loaded Macbook SR 2.2. I was doubly happy that I finally showed some discipline and refrained from spending a small fortune on a Macbook Pro. I figured I would do no gaming, except a little WOW (which I have not tried yet - gulp) and no professional level software, especially media related. What I would do is go to town on iLife. I'm finally trying out iMovie and put together an awesome video/photo slide show with music and all of the little transitions ... BUT, when I try to play it back, my Macbook hiccups, coughs, stutters and skips through the sequence of my photos and videos (especially in full screen mode) - i.e. it does not play it smoothly. Is this normal? I'm starting to get worried that the Macbook can only handle very basic office applications and Internet browsing and starts to buckle under the slightest pressure, even with the built in iLife suite. Is this just an issue of adding RAM (I only have 1 GB). I'm planning to bump it up to 4. What limitations do I simply need to accept on my once glorious and now very humbled Macbook?
