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
Since driver version 1.27 PID 8192 can be used pass through entire transport stream.
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 issues with version 2 chips on ID 0485:9135 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. The reverse also applies.
