I did a little bit of testing using Camstudio program to record the video of WinSPWW2 game. I set the game to run at windowed 640x480 resolution and used the Camstudio to record the window.
The first video is captured using the Microsoft Video 1 codec. Because of the 23 MB size limit for attachements it is a short clip. However it shows that the game can be recorded in good quality using Camstudio.
EDIT: Or I could just ZIP to a 5.26 MB size...
