I have managed to get my Compro DTV T-300 DVB tuner card to work on Linux Mint 12. This card has a S-Video input as well as a Composite video input and a combination analogue tuner and Digital TV tuner card. I am using the Me TV software available for Linux Mint and the software was able to tune in some channels. Below are the settings I am using for this card that I have typed into my /etc/modules file. So if you have one of these cards, give this a try and see how successful it is for you. The card running on Linux will not tune the channels as well as it will on Windows, but at least it works, and I may watch a little television without too many problems. This card works with the tvtime software, but that will only use the analogue tuner and that can not be used with my computer as you need the CD Audio connector from the card to the motherboard, but I can not get that to work with my Gigabyte H55 motherboard at all. So the DVB option is the only one. And analogue television will be switched off this year anyway. Just set up all of this and then launch the me-tv application and it will walk you through scanning for channels and saving them when it is done. I am using a vanilla kernel from kernel.org, 3.2.9, but I am pretty sure that this will work with the default Linux Mint kernel as well.
The card works out of the box with Linux Mint 13 – 15, the modern kernels and distributions do not need any extra configuration to use this television card. But if you are using an older Linux distribution then this code listing will help you out.
