Tvheadend

Hi there,

I am currently using Argus TV as my PVR backend with three Raspberry Pis running LibreELEC.

I have lots of good things about TVheadend recently and am dying to give it a go - especially, given that it has been called the unofficial PVR backend for people, like me, using Kodi only clients.

I have only had limited experience with Linux before and did try MythTV - I really struggled to get it up and running.

I have just a few questions before I try and give TVH a go at the weekend:

1. Am I correct in thinking that TVH can allow me to timeshift Live TV to a RAMDisk via a ring buffer (which I currently do with Argus)?
2. I currently have three Hard Drives in my server. I use a piece of windows software called Stablebit Drivepool to no only make them drive pool them but to balance recordings between the drives, based on I/O activity and space available. As I would be losing this, moving to Linux. Is there are any equivalent software that I might use?
3. I note that TVH is able to make use of series record, which is something that was never implemented into Argus. How does this work and does it rely on me getting my EPG from a particular source (I assume, one that contains CRID information) - I am in the UK, btw.
4. My two tuner cards are these:

As a complete novice to Linux, am I going to have to do anything extra to get these working with TVH or will they work straight out of the box.

Thanks in advance for any help.
