under ms windows:
there is *no* need to get the firmware file !
it's hidden in one of the drivers files.

if look in the script-file *get_dvb_firmware* (part of the kernel
documentation or google is your friend) you can see that this script
downloads the driver for your card from the internet and *extracts a 
part* of a special file.

under linux:
according to your card: you need the firmware file !

i would like to say it's always binary.
(for me) it's like a bios-file for the computer's bios.

try under linux: file <your-firmware-file> or
the hard way cat ...

i hope it's adequate. let me know, if *not*.
