Multiple HDHomeruns on a Synology DS213

Chris N

Hi. Is there a way to set up multiple HDHomeruns on my Synology DS213? I have 2 HDHomeruns (4 tuners) and a couple of Hauppauge HVR-1950 tuner's attached to my Synology DS213. I am running Eric V's tree of TVHeadend on my NAS because this version supports timeshifting and I need a version that I can compile in order to get the analog tuners to work. I'd like to be able to compile the latest version of TVHeadend, but I read somewhere that I can't until Synology updates their toolchain. Currently, only 2 out of the 4 HDHomerun tuner's are working. The analog tuners are working fine. TVHeadend shows that 3 of the HDHomerun tuners are available but only adapter0 and adapter1 will find services. Adapter2 is unable to find any services and adapter3 is not showing up at all. I tried installing the HDHomerun SPK package, but got the same result. Any idea's?

Ok, I found that the problem is in the startup script.

DYNAMIC_ID=$(grep hdhomerun_control /proc/misc | awk "{print $1}")

creates a variable that contains " 57 hdhomerun_control", but it should only contain "57".

I added DYNAMIC_ID=${DYNAMIC_ID:0:4} after this line to correct it.

Also,

DYNAMIC_ID=$(grep DVB /proc/devices | awk "{print $1}")

creates a variable that contains "212 DVB", but it should only contain "212".

I also added DYNAMIC_ID=${DYNAMIC_ID:0:4} after this line to correct it.
