The HVR-1250 PCI-Express x1 card supporting video capture over NTSC, ATSC/QAM, and S-Video. This is a 'hybrid' tuner, meaning that both analog and digital capture is handled by the same hardware, and the two cannot be used simultaneously. At the time of writing (Mar. 08), this tuner can be readily found for $50.
Until kernel 2.6.24, there was no in-kernel support for this card. V4L and DVB must be disabled in the kernel, and the drivers compiled from the source at v4l-dvb. Under Gentoo, this is with the 'v4l-dvb-hg' package. The drivers currently only support digital capture. Tveeprom will fail while trying to load the analog firmware, but this does not affect digital operation.
Unlike other Hauppauge products, this card does not have a hardware encoder for analog video. Consumer forums claim that the video quality (in Windows) is poor. While this would compliment existing PVR-150/250/350/500 cards well, the HVR-1800 is a better choice if future analog capability is desired.
