I2C errors are often a symptom of missing or wrong firmware. I have<br>
had tuners seem to work with missing firmware (the device appeared<br>
under /dev/dvb), but they did not actually work properly. So did you<br>
install the latest firmware for each of your tuners on the new system?<br>
It is easy to forget that you have had to install firmware files, so<br>
when I move tuners to a new system, I use a file diff tool between the<br>
old and new systems on the /lib/firmware and /usr/lib/firmware trees<br>
and copy across anything that is missing.<br>

I never used the older Pi processors, so I am not sure if it will work<br>
or not. But it is certainly worth trying as minisatip is designed to<br>
work with very low resources. You may have problems finding drivers<br>
that will run on the Pi ARM processor though - if they are kernel<br>
builtin drivers, you should be OK, but ones provided by the<br>
manufacturer might be a problem.<br>
<br>
There are DVB-S2 USB tuners. I have an old one (TBS5922), and TBS<br>
have some current options:<br>

<br>
They are not cheap, and you would need to check the requirements for<br>
the drivers. I have to compile drivers for my TBS6209 and TBS6909<br>
cards each time the kernel is updated.<br><br></blockquote><div> </div></div></div>
