Yes, that's great, thankyou.  It looks like the firmware hasn't got compiled 
into the module since the zeros in the middle of this line:

are the size of the firmware.

Here's what to do:

Check you have the firmware in the right place and with the right name:
/etc/dvb/dec2000t.bin
Probably worth checking that it's not zero file size, and that you have 
permissions to read it as the user you intend to build the module as.

In your dvb-kernel/build-2.4 directory:
make clean
rm dsp_dec2000t.h

Then make and install as usual.  Once it's done, you can check things further 
by making sure that there's lots of data in dsp_dec2000t.h and ttusb_dec.o 
should be at least about 0.5MB.  Also, check that the module has installed 
properly and is the one you've just built. It should be in:
/lib/modules/your-kernel-version/misc/

Good luck,
Alex
