This almost seems like a duplicate post, but the other one already is marked as Solved with a Best Solution chosen. So, maybe you can't continue with the old thread.
The original post concerned trying to use a PCI intex SAA 7130 TV tuner card. It's an old design and so there are questions about whether or not there are any device drivers for it for the Win 7 OS.
There is another type of question, too. I do not know where OP is located. Throughout North America, broadcast TV changed to using DIGITAL signals back around 2009 or so. This means that any tuner card for use with Over-the-Air broadcast signals in North America will have to be able to work with that signal system, and this old tuner card can NOT do that - it handles only older analog TV signals. Now, there may be ways to avoid that problem even if you are in an area using digital TV signals. First, you can buy or rent a tuner / converter that tunes the new digital TV signals and outputs the older analog signals which can be fed into such a tuner card. Alternatively, many cable TV systems include a set of channels carried in the older analog format for people who have only an old TV. In either case, doing this involves some way of using an external device (the stand-alone tuner box) to select the right channel, rather than using the computer's tuner card itself (under software control) to select the channel.
So, OP, you may have two problems to solve if you want to use that old card. One is to find a device driver for it that works in Win 7. The other is to figure out how to get the new digital TV signals into it IF that is the type of TV signal available to you. It MIGHT be simpler to get a new tuner card.
