Install the firmware and driver as stated above. If there are artifacts, unload and reload cx23385 with modprobe and restart mplayer/tvtime.Īccording to the MythTV wiki, analog is not supported due to driver issues. Mplayer /dev/video1 -vo x11 -nobps -autosync 30 -forceidx -hardframedrop -vc ffmpeg12 -idle -menu -cache 16384 -cache-seek-min 50 -mc 0 -ni Run tvtime as normal user (tvtime -v), configure with proper settings for your region and scan for analog channels. Mplayer uses /dev/video1 which is encoded mpg2 with audio. Tvtime uses /dev/video0 which is raw video signal so it can change the station. Tvtime will be used for switching channels while mplayer will be used for watching with audio.

Note: I have spoken to support in the MythTV-users IRC channel and they say the driver support / MythTV combination just doesn't work, and that the driver's author is aware of the issue.
To get analog to work, follow the steps as shown in How to build from Mercurial up to "Build the Modules" and build the driver.Īfter "make install" is finished and if the system has loaded the default kernel's module, unload it with:
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. In any regard, the very small quantity that were produced are indeed supported by LinuxTV drivers. Whether or not this low profile HVR-1800, or a revision like it, is ever released for mass production is still unknown. However, as it turned out, it was the full-height HVR-1800 rendition discussed above that was widely released. When information about a "HVR-1800" model first became known, photos accompanying this news were of this low profile card.

The card also sports an A/V header, which allows for additional inputs when It features three RF inputs (one for analog TV, one for digital TV, and one for radio). This dual tuner card is also known as model 1129 and has a Subdevice ID of 0x7800.
