Sorry to tell you that I don't know any TV tuner application that is free and applicable regardless of the manufacturer.
I do think that there will be more than 1 application software, or 1 with 2 or more versions, downloadable on the web.
Once my TV tuner software got crashed, and I uninstalled the version come with the package, then installed the latest version, and fixed the problem.
Hope you can solve yours soon as well.
