This is actually strange because the Wiki states that the card is using an 
"NXP TDA10048 digital demodulator" 
(http://linuxtv.org/wiki/index.php/Hauppauge_WinTV-HVR-1120). Anyway, this may 
worth the cost to build an old kernel to see if this effectively works well ;)

I have tried several scenarios :
 - the last 2.6.36 Linux kernel
 - the kernel 2.6.35 with sources from the HG repository 
(http://linuxtv.org/hg/v4l-dvb/)
 - the media tree git (http://git.linuxtv.org/media_tree.git)

In all situations, I get the same behaviour. After a random number of reboots, 
the TV (DVB-T) is not working and I get this message displayed in loop in 
`dmesg`:

tda18271_write_regs: [1-0060|M] ERROR: idx = 0x5, len = 1, i2c_transfer 
returned: -5
tda18271_init: [1-0060|M] error -5 on line 830
tda18271_tune: [1-0060|M] error -5 on line 908
tda18271_set_params: [1-0060|M] error -5 on line 989

Also, even when the TV is working, I get these error messages in `dmesg:

[...]

I may take a look at sources to understand what is happening. So, if someone 
have an idea, please tell me ;)

Thanks,
