Installation Instructions

Kernels 2.6.31 to 3.3 and updates
Go to the How to Obtain, Build and Install V4L-DVB Device Drivers page and download and build the lastest media_build.
Driver last updated: 03 MAR 12
Driver Version: 1.27

DVR Applications

When using digital video recorder such as VDR, MythTV etc turn pid filter off.
Modify /etc/modules (or /etc/modules.preload) file and enter example;

 dvb-usb-it913x pid=1

Known Problems

Slow channel change.
Signal Level / SNR level level incorrect.
PID filtering issues on some networks.
Does not work with w_scan with PID filter on. Use the -F option

w_scan -F

Issues with 9005 type devices.
Chip Version 2 on ID 048d:9135 does not tune (fixed from driver version 1.24).
Kernels 3.2 and 3.3. A stable backport is planned for these kernels shortly to resolve
issues with version 2 chips on ID 0485:9135. In the meantime update with media_build.

Warm boot from other places

Users should not reboot between operating systems without a power off cold boot. Some devices may have different tuner registers and firmware applied. The two should always match.
