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.

There was talk of NTSC analog support coming soon in September 2007, but as of February 2009 nothing has come of that. Unlike other Hauppauge products, this card does not have a hardware encoder for analog video, instead acting as a framegrabber. If analog support is desired, IVTV cards are the recommended capture device.

As of LIRC version 0.8.4a the IR chipset used in this cards Infrared (IR) receiver is not supported. You will need to purchase or make a separate IR tuner to use it's remote control.

Comments

-- This card should be supported in kernel 2.6.24 and up. I purchased this card, dropped it into my MythDora5 box running 2.6.25, and was capturing HD television within Myth from a pair of rabbit ears, with configuration taking 20 minutes. ~frostfreek, Jan 2009

Some recent versions of this card do not work with stock kernel (as of 2.6.30) and require the latest v4l-dvb drivers. These cards are identified as HVR-1270 by the driver.
