Yup. That's enough to get started. Usually these internal TV capture cards are on a mini-PCI card accessable via a door on the bottom of the laptop. But these cards are also often covered with a metal can, so it's impossible to see what chips are on them without damaging the metal can. So we'll do our best without any pictures. I'm going to assume your internal card is using an Xceive XC2038 or XC3038 silicon tuner which has it's own firmware. Can you see if there's a file named something like ....028.rom provided by the Windows driver to verify?
