[vdr] xineliboutput X11 window has nearly invisible menus

Hello.

I set up VDR (1.4.7) with xineliboutput (1.0.0~rc2) on a VIA EPIA SP-8000E. For xineliboutput I use an X11 window with the xxmc driver. X is set up to do TV out (PAL) via the composite jack. My problem is now that I can barely see the menu on my TV. The menu is very transparent and no option in the plugin settings menu seems to change this. Interestingly the menu is all right when viewed via vdr-sxfe. There I can toggle transparency and adjustment but it doesn't have any effect on my TV.

Is this a known problem or has anyone any tips for me? Searching google and the list archives didn't yield anything related.

I'd appreciate any help, Tobias
