I dont think this is possible it would cause a huge drain on the system resources.
You would need 2 capture cards to work independantly, otherwise just capture from first then the other.
Dont know if this is what yoru looking for but check it out
DirectX Video Stream and frame capture
http://www.codeproject.com
only one idea if you can see both the web cam images running on your desktop at the ame time,
try capturing them in cam studio, I have not tried this but since its actually going to end being just one capture of 2 webcam screens side by side should work okay.
You can also choose the regeon size of the capture.
CamStudio is able to record all screen and audio activity on your computer and create industry-standard AVI video files and using its built-in SWF Producer can turn those AVIs into lean, mean, bandwidth-friendly Streaming Flash videos (SWFs)

I already build a system like that a few year ago with directshow.
If you are looking for examples and C++ code, have a look at DSVideolib c++ library
http://sourceforge.net/pro
no problem for directshow to handle multiple cameras. The only problem is the timing reference, do you need frame synchronized recording ?
"The problem that from one source I get real-time frames ~30 frame/sec but from the other I get frame rate of 2-4 frame / sec"
--> i your system does'nt have enough ressources, frames drops will occure, try not to use live compression at first (MPEG2 / MPEG4, ...). for example use YUV capture and huffman encoding.
Or simply try displaying it on 2 different windows.
Maybe you didn't configure properly you're webcam inside graphedit. verify the capture settings in the "webcam" filters.

2 WEBCAMS AT THE SAME TIME?, WHAT SOFTWARE YOU PLAN TO CAPTURE WITH?.
