Problem when I change the live channel in mythtv


New member
Hi, I have a problem with my chipset ATI RS690 with RADEON X1200 Series video card ( inserted a KINO-690AM motherboard) when i used mythtv. When I change the channel , the image becomes made as diagonals, when the resolution of two channels change (example when I pass from 704x576@64 resolution at 720x576@64 resolution that second channel or vice versa).Someone can help me?
Thanks peppino.
