     09.05.2007 Lutz Koschorreck
     First version: Tested with ivtv-0.10.1, xine-ui-0.99.5, xine-lib-1.1.6
-
+    20.05.2007 Lutz Koschorreck
+    Some Scaling and zooming problems fixed. By default the vidix driver now 
+    controlls the setting of alphablending. So there is no need to use
+    ivtvfbctl anymore. To disable this feature set the following environment
+    variable:VIDIXIVTVALPHA=disable. Special thanx to Ian Armstrong.
+    23.07.2007 Lutz Koschorreck
+    Support for 2.6.22 kernel added. PCI scan added.
+    07.10.2007 Lutz Koschorreck
+    Restore old alpha value correctly. Fix capability struct values.
