[QUOTE="mironicus, post: 257671, member: 69593"] [b]Crash Report[/b] The flickering is causing that Mediaportal freezes sometimes on my computer. The bug is reproducable for me. If you go to MyTV, switch TV on. Repeat this several times: Go to timer and go back. The screen in "Timer" flickers heavily (between black and blue). After some switching Mediaportal won't go back to the MyTV-menu and freezes. Look at the screenshot down under. I attached the error report for my system. This is the main error: [code]008-04-20 14:33:29.416000 [ERROR][17]: render exception:System.ArgumentOutOfRangeException: Index was out of range.
