As you already have noticed, the vendor kernels often have "features" 
that break the compilation of drivers, that are compiled "outside" the 
kernel.

Please note that the developers cannot test the driver under all 
distributions. It's good when the users (ie. you and me) do this and 
share their results with the rest of the mailing list.

So, do you use the binary image from RedHat or did you compile your own 
kernel from the kernel sources from RedHat?

I you don't know exactly what you are doing, then this is a waste of time.

Most likely the module loader cannot match the functions symbols, ie. it 
looks for "videodev_register", but the kernel only has a function called 
"__foo__bar__videodev_register". Have a look at /proc/ksyms

When you have compiled the modules into the kernel, where do you get the 
videodev.o from? From the kernel source directory?

You have two options:

1) Get a fresh kernel from kernel.org and try to find out how to install 
that one under your RedHat system. Of course this won't help the other 
users out there, who are not experienced enough to install a kernel on 
their own.

2) Install all necessary kernel-source RPMs from RedHat and try to fix 
the compile script. If you don't get along, ask on the list again and 
post the *exact* compilation error you get. You might also try to use 
"dvb-kernel" CVS driver instead of "DVB", because it uses a different 
build system.

If you choose 2), it's likely that the compilation problems can be 
fixed. RedHat does not use voodoo, but you have to understand what they 
have changed in the kernel and in the compilation process.
