The AVerMedia A771 is a, so called, budget or software decoding PCI DVB-T card. These cards work well with the latest kernels.
It is the successor to the original AVerTV DVB-T card, the A761 model.
Overview
The AVerMedia A771 features:
- a MT352 demodulator ... The first few versions of the MT352 driver didn't work so well, so try upgrading if you have problems with tuning.
(mt352/samsung tdtc9251dh0(??))
features: Card is capable of delivering the full unmodified TS stream to userspace. AVin card driver: dvb-bt8xx interface: PCI PCI device id: 109e:036e PCI subsystem id: 1461:0771 Bridge: Brooktree bt878 frontend 1: tin box: samsung tdtc9251dh0 frontend driver: mt352 demodulator location: tin box demodulator: mt352 @0x0f PLL: ?? @0x61 Notes:
Kernel configuration
If building your own kernel, you would want to select all options under "I2C" and all options under "Video for Linux" (incl. "DVB", obviously).
AVerMedia actually wrote a nice HOWTO for Setting up an AVerMedia A771 DVB-T card under Linux ... likely very dated by now, but worth a look. AVerMedia's guide is nolonger on their site, but it can be found on Archive.org
After compilation, to get the card to work simply call "modprobe dvb_bt8xx". Then run, "scan" (from dvb apps) or MythTV as normal.
