TVButler with software or without?

Hi,

Please pardon the likely very simple question but I am looking to use this DVR and live TV lark through Plex and as part of that was going over the list of things I’d need.

I believe I don’t need an antenna as I have a TV aerial in the house that’s fairly recent so will be digital.
I also have Plex on a small mini pc and a DS414 NAS so I could plug a tv tuner into either I suspect, the tuner I was tempted to grab was the DVBLogic TVButler 100TC however on amazon it has Tuner only and another that includes software.

Do I need the software one or is Plex effectively my software?

Thanks in advance.

Hi,
Did you get an answer to your question?
Is the software required additionally or is the USB TV stick sufficient for 50€/$?
