KODI is not great for live streaming. The IPTV apps work better for that. You can use the IPTV app in KODI but it's only fair. KODI is great for what it is but it does have it's limitations.
If you could reverse engineer the DTV P4 card, you could get all that free but.... alas, LOL
Cable prices are usually crazy. At least in my area. You might look into Amazon Prime TV and/or Youtube TV. There are several others who offer select channel offers. e.g. if you just want the Food Channel and the History Channel, you just buy those 2. No need to pay for all those channels you don't watch.
Just something to check into.
Cut the cable.
