Channel change problems with Twinhan DTV Sat-CI

[mitsu]

With the latest DVBViewer Pro channel change behaves a little strange with Twinhan DTV Sat-CI.

 

Cases:

- Sometimes channel change is very fast

- Sometimes channel change last around 5 seconds

- Sometimes change can take 15 seconds but is successful at last

- Sometimes channel show black screen forever but succeeds after rebuilding graph

- In certain cases after quick channel changes back and forth even rebuild graph shows only black screen. But changing to another channel works normally.

- Worst case happens only with Conax-crypted HD channel (C-More HD). Sometimes black screen cannot be corrected without restarting DVBViewer. Reboot is not needed. In this case processor load stays constantly on around 55% until restart (Pentium 4 3.0G hyperthreading). Normal DVBViewer load is 10%.

 

Basic cases are the same with free channels and Conax crypted channels. Enabling and disabling fast channel change changes behaviour a little but the cases are still the same.

 

Bad thing here is that timer recordings are not reliable anymore.
