Having just been through this with my hdr-2200 I can perhaps give some clues.

The biggest problem I had was that the tuner module wasn't being loaded
correctly. No tuner = 100% signal reported but nothing found. The symptoms
I had of this was the following:
 # grep symbol /var/log/messages
Oct 18 07:47:36 jupiter kernel: DVB: Unable to find symbol tda18271_attach()

In my case it was my own fault - I'd blacklisted the tda18271 module
because my USB tuner (which uses the same tuner) wouldn't cold-plug
correctly and I wanted to load its modules manually. Try the following to
see if its loaded OK:
 # lsmod | grep tda18271
tda18271               43260  2
i2c_core               12520  20
tda18271,tda10048,dvb_pll,stv0299,lnbp21,tda826x,tda10086,nvidia,saa7164,v4l2_common,videodev,b2c2_flexcop,budget,budget_core,cx24123,ttpci_eeprom,cx24113,tveeprom,s5h1420,i2c_nforce2

If this is the problem then stop the backend, unload the saa7164 module,
load the tuner module then the saa7164 back again.:
 # /etc/init.d mythbackend stop
 # rmmod saa7164
 # modprobe tda18271
 # modprobe saa7164

If its not the problem then duh!!!!
