Tvheadend

Hello,

I am about to give advise to my farther to either buying a Synology NAS or build a FreeNas system (which I definetly prefer).

How ever there are some issues that after a google research remain (for me) unsolved. So please do not recommend me to do a forum search because I already did it and didn't find a suitable answer.

Moreover I know that there is an existing plugin for plex integration with Freenas, so that would be considered as solved.
However we populate our media library via dvr / digital video recorder, (for instance Mythtv or tvheadend) and with regards to my farthers wish to have ONE server that includes this dvr feature too I wanted to ask if there is a working / stable and reliable solution for FreeNas? Or am I forced to go with a second linux server for recording (which is sadly a dealbreaker for him).
I would get the tv signal from a DVBS2 usb card.
Here is the tuner card we plan to use:

It seems to appear in this list so is there any hope since FreeNAS is based on freebsd I guess.?

Thank you for your attention!
