I’ve finally recorded a playthrough of InSight.

I ran the game on the Windows 7 side of my MacBook Pro, and did the recording from the OS X side (I was running both operating systems simultaneously using Parallels). The trouble was that apparently MacBook Pros can’t record sound directly from output streams, only input streams. One solution is to reroute an output stream to input and record from that input stream. I did this using some software called Soundflower, which is free online.

You can watch the playthrough here: https://www.youtube.com/watch?v=Hqt1jCmi1uU

If anyone familiar with OS X has a better solution, let me know in the comments.
