An ATSC PCIe card from Hauppauge.

Support for the WinTV-HVR-1250 card's digital TV reception capabilities (8-VSB & 64/256-QAM) is currently provided within the latest drivers from the LinuxTV Hg repository, and should make its way into the 2.6.24 kernel. Analog support will be added in the near future, but it will likely be too late for inclusion into 2.6.24.

Overview/Features

Discuss the features and facets of the device here ... this means you

The HVR-1250 is also known by its codename Coram.

Components Used:

• ? (tuner for analog ... likely a NXP/Philips TDA18271)
• Microtune MT2131 (tuner for digital)
• NXP/Philips TDA8295 (analog IF demodulator)
• Samsung S5H1409/Conexant CX24227 (digital demodulator)
• Conexant CX23887 (A/V Decoder & PCIe bridge)

Identification

provide the relevant output of lspci -vvn or, in the case of usb devices, lsusb -v here ...we're particularly interested in the subsystem IDs ... this means you

It has a Subsystem ID of 0x7911.

lspci -vvnn gives

Remote Control Support

discuss support for the remote control here

Testing

use scan to get the initial channel list required by [azap]

use azap to tune to the desired channel

use mplayer to watch the channel. Be sure to copy the channels.conf file from the initial scan to your ~/.mplayer directory

mplayer dvb://"Channel Name"
