FRAPS doesn't use compression nor render, it sounds nice for lower end processor, but suck alot of hard drive memory.
It is about 436MB consume for using 23 sec, about 1.7 GB for 90sec at 1024x768 with sounds. It isn't the solution you are looking for.
Maybe camtasia studio, they get a lot of codec, but your processor must bepowerfull enough. You got plenty of codec when you use their software, and you can download third party codec. This is your solution depending how powerfull your processor is.
