Linux QAM256 works / QAM64 does not... on Tvheadend 3.4 and HDHomerun HDHR3-4DC
#5
Going to buy a Humax IHDR-5400C and see if a consumer grade decoder can handle the QAM64 streams.

To be continued...

UPDATE: QAM64 works fine on the decoder. I've upgraded the HDHomerun to the latest bleeding edge beta firmware. Made no difference. Then I started screwing around with the settings. I had the dvbc modulation set to a8qam64-6875 a8qam128-6875 a8qam64-6875 which is what everyone else in my country uses. The command was this:

hdhomerun_config **my device id** set /sys/dvbc_modulation "a8qam64-6875 a8qam128-6875 a8qam256-6875 "

This is the exact same thing that the Windows Setup does. Thinking, what the heck, I set all three options to QAM64

hdhomerun_config **my device id** set /sys/dvbc_modulation "a8qam64-6875 a8qam64-6875 a8qam64-6875"

Which didn't seem to have an effect. Then I tried

hdhomerun_config **my device id** set /sys/dvbc_modulation "a8qam64-6875"

..and.. BAM.. everything works fine. All channels are instantly accessible. Hell, even channel switching is faster. This makes absolutely no sense as these settings would mean I lose all QAM256 channels but this is not the case.

Weirdness...
