You will know that every time a new Kernel is installed, the old kernel
media modules must be destroyed while booted into the old kernel.
Then after rebooting into the new kernel, new modules must be compiled.
It is a pain in the proverbial a..e.

So I developed a script to automate the process. Read the instructions
at the top if you plan to use it. There is no guarantee that it is
perfect but I have tested it but on;ly on Mint 21.1

Here it is:

#!/bin/bash
# sname="Install Open Source TBS drivers (tbs_osrcupdate-07).sh"
# --------------------------------------------------------------------
# This script automates the process of installing dtivers for TBS TV cards
# such as TS-6280, TBS-6281 etc, particularly following a kernel update.
# It is a two-pass process. Start it while running the original kernel.
# Following a reboot into the new kernel, run it again.
# # Created by Alan Secker 2023, based on an open source script provided by
# TBS. It has only been tested in Linux Mint 21.1 but should run on any
# Linux system provided the kernel hearders or sources for the new kernel
# have been downloaded and installed.
# # No warranties are given. Run it at your own risk.
# =================================================
# Before running this script:
# # 1) Create a directory TBS-TV in your home directory
# 2) Move this script to ~/TBS-TV.
# 3) Make this script executable by running "chmod+x tbs_oscrupdate.sh"
# from a terminal prompt ($) without the quotes.
# 4) If not already installed, from a terminal, run sudo apt install git
#
