game video capture

[maxchen]

Hi guys !
These days,I played a lot custom levels and stuck in them sometimes.At that moment,I tried and fail and tried again.........It must be a lot people like me.If there are some video to the place that most people stuck in,I think,would be wonderful.After searching for a video capture software on the internet,I finaly found the best two:Fraps and GameCam.Unfortunately,Fraps makes the computer very slow and the output video with huge size!I think GameCam is the best one!But it just suport the DirectX 7.0 or above and OpenGL games.The bad news is TR custom levels use the engine of the TombRaider-TheLastRevelation which is using DirectX 6.1.So the problem is can we modefy the tomb4.exe and make it run with some DirectX 7.0 ,8.0,9.0 or OpenGL functions?Or code a litle program that call some functions of the DirectX 7.0 ,8.0,9.0 or OpenGL and run with the TombRaider game.I think the best way is code a dll file which call the function that make GameCam work,after running the game ,we inject that dll into the game's process.And this will make no change to the tomb4.exe file.
Here is GameCam's homepage:http://www.planetgamecam.com
And here is link to my litle TombRaider website
