no its a problem with the skin .. it works fine if you switch skins ..
try getting a different skin .. go herehttp://tortoisesvn.net/downloads
download that ..
put this in as the address when you install that app ..https://svn.sourceforge.net/svnroot/xboxmediacenter/
than pick a new folder, right click on it and hit update SVN .. it will download alot of skins for XBMC .. once its done you have to run BUILD.bat in each skin, it will create a build folder which in that contains the skin .. the skins are updated fairly often so to update just right click and hit update again, it will only get the updated files .. enjoy :]
edit: and here is the UNOFFICIAL fix to the PM3 skin ..
"I just was able to fix it in PMIII. i did what they say! in home.xml under the DVD-Rom Buttons, i removed the second DVD Button, and i deleted the
"System.KaiConnected"-order in the Dvd-Rom button section. So finally i had just one DVD button whitout a "system.kaidconneted"-order, and the Kaid Button..." - CHDude
T3CH only compiles XBMC and has NOTHING to do with bugs .. try here .. www.xboxmediacenter.com .. make another bug report ..
