Actually my ddbridge driver from Digital Devices Cine S2 is also reporting with different values. Actually it reports the strenght and quality in percentage where 100% are 2 bytes.
So what I did to get the nice view I change the values in src/input/mpegts/linuxdvb/linuxdvb_frontend.c as follows:

mmi->mmi_stats.unc = u32;
}
SNR is not in db anymore but in percentage, thus I change the object in the src/webui/static/app/status.js, to avoid this, it would be nice to understand what 100% are in db? is it 16,5? 18? or 20?

I know this is quirk, but at least is it working for me...
I'm using SMP Debian 3.2.51-1 x86_64
