    When I watch live TV and change the channel, my PC changes resolution from 720P50 to 480P60? Automatic refresh rate change has not been activated in MP configuration.

    It seems that I can change the channel freely inside one DVB mux, but when I select a channel belonging to another mux this happens. This line is visible in MP logs, but what triggers the change?

    Hi putkonen,

    I may be missing something but where in the log do you see that the screen resulution goes down to 480?

    Hi putkonen,

    My TV shows the new resolutions, and after exiting MP I could see it also in XP desktop.

    However, I fixed the issue yesterday. I had to add 720P50 resolution to Windows Display Manager from ATI CCC, and then choose 720P50 from Windows display manager. Now it works. Strange!
