after navigating some trouble with installing Linuxmce on my computer (mainly graphicsdriver issues) I tried to configure mythtv. At first no setup showed up, but when it finally did, I was able to configure the DVB-S card and search for stations. However I cannot watch TV. Backend seems to be crashing all the time, all tuners are supposed to be busy. I also cannot access mythweb. I get only an imcomplete webpage, like shown in the screenshot.
