Support for the 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 for the WinTV-HVR-1800 (which is currently contingent upon the addition of such to the CX23385/7 driver) will be added in the near future, but it will likely be too late for inclusion into 2.6.24.
Full-height Version (a.k.a Medford)
This dual tuner card is also known as model 1129 and has a Subdevice ID of 0x7800.
It features 3 RF inputs (one for analog, one for digital and one for radio). The card also sports an A/V header, which allows for additional inputs when when used with PC cases that have built in front or rear panel A/V connectors (S-Video, Composite and L/R Audio).
This card features:
- NXP/Philips TDA18271 (tuner for analog)
- Microtune MT2131 (tuner for digital)
- NXP/Philips TDA8295 (analog IF demodulator)
- Samsung S5H1409/Conexant CX24227 (digital demodulator)
- Conexant CX23417 (MPEG-2 encoder)
- Elpida (RAM)
- Conexant CX23887 (A/V Decoder & PCIe bridge)
Half-Height/Low Profile Version (a.k.a Brentwood)
When information about a "HVR-1800" model first became known, photos accompanying this news were of this low profile card. However, as it turned out, it was the full-height HVR-1800 rendition discussed above that was widely released. Whether or not this low profile HVR-1800, or a revision like it, is ever released for mass production is still unknown. In any regard, the very small quantity that were produced are indeed supported by LinuxTV drivers. This card has a Subdevice ID of 0x7600.
This card features the same components as the later full height version (see above) with the exception that a NXP/Philips TDA8275A tuner was used for analog, as opposed to the later card's switch to the NXP/Philips TDA18271.
