[linux-dvb] After instal v4l-dvb other v4l modules don't work

[Pascal]

Hi.
I have a Terratec Cinergy XS T Usb, and it works very well with the em28xx, 
em2880-dvb modules.
But my webcam, doesn't work (it works before the installation of v4l-dvb).
After the compilation, when i run
sudo modprobe gspca
this is the output:

[17183190.408000] gspca: disagrees about version of symbol video_devdata
[17183190.408000] gspca: Unknown symbol video_devdata

I've tried also with the ov519 module, and the result is the same. This module 
too worked well before the installation of v4l-dvb.

There is a way to work with the videocard and the webcam?
Thanks!

P.S. Sorry for my english...
