Wat is da max Vid Record size?

What is the maximum size Camstudio can record? I tried recording a 15 min vid made up of 5-6 min vids. After it was done recorded it compressed audio as normal but when that is done I get an error message saying " unable to open movie". The size of the file was more than 2 Gigs when it was done! It is in AVI Format. Camstudio works fine except the length of vids are limited.

It depends on the limitations of your computer. As Camstudio records it slowly sucks up more and more RAM, CPU cycles, and disk space. Try viewing the video in a different media player (try VLC [google it]), it seems that it's just using a codec you don't have. You should also install the K-Lite Codec Pack (again, google it). Both of those are free. If that doesn't work, come back and I'll help further.
