The old hauppage TV tuner cards work great with Linux. I actually have some old-school hauppage (old 4:3 TV signal) tuner cards and they work great under a modern Ubuntu install. I also use a couple of hdhomerun units (which do hd) and they don't really require drivers and also work fantastically with Linux. With Linux the drivers are (mostly) part of the kernel. If they don't work, it usually means that they're very new. Linux driver support is leaps and bounds better than any windows support, which is usually discontinued and forgotten about.because the companies go out of business and have closed-source drivers. Linux drivers are open source and if they don't work, the community fixes them even if the company goes under or hasn't been around for decades.
