You'll get smaller file sizes rendering to WMV or MPG. I assume that you're rendering to AVI. These are typically very large because they do not compress the video. If you're rendering to CD, use the built-in VCD or SVCD formats for rendering that are found in the MPG-2 render type.

MOV files are extraordinarily large with the provided CODEC. I don't understand this, but I don't render MOV files so Iknow little about this.

Re: File order. What do you mean by this? Are they out of order on the timeline? This might be caused by having insufficient memory, but I'm just guessing. You should have at least 2 GB of ram in your rig. Also, which edition are you using? The pro or the standard edition? And what version number, and whcih Windows are you using?
