Rollercoaster Tycoon 3 & Camtasia

Back in November, TechSmith was offering Camtasia 3.3 to teachers for free. Unfortunately, the offer is no longer available. I see lots of possibilities for Camtasia, though I could wish it was just a little easier to use. I think one of my problems is that I have a wide screen laptop, so when the software tries to set a region automatically, the measurements are off.
I then used Camtasia to record my screen while I played with RCT 3. I've never been really happy with the tutorials in the software, because they are very limiting, and in this version, require a lot of text to be read. It is hard to go back if you miss something, and there is no audio. In the past, I've tried to record the action on the screen using an S-Video hook-up to a TV with VCR, but it didn't work as well as I had hoped. I was able to produce a basic video that shows how to place a "ready made" ride, and some facilities. The version here is of low quality so it won't take forever to load: the original is 1 GB without audio. I just figured out how to do the audio, and so will probably try that next. Now, if only getting RCT 3 learned was that easy; as with the other versions, the thing I find hardest is placing the paths.
