Ok, so the old dp had no problems compiling. However, now the new dp has an error. What needs to be done so I can compile without the error.

This is because nobody maintains the Dev-C++ and the Visual Studio project files.

Try using the Makefile, or add the files cap_ogg.c, cap_avi.c, hmac.c to the project and compile (and submit the new project file so it can get updated).

Why don't we simply remove the project files when they never work anyway...

They worked last time I checked (VC one).

They got updated two days ago or so..
