Thomas,

Your patch is a good start towards getting this fixed, but it's not working correctly yet. I noticed you said it was a rounding issue, can it be fixed? In case you think that decreasing these values by just a few points isn't bad, remember that the values get decreased upon *each* invocation of totem (and possibly other players), again and again. After about 5-6 invocations, totem causes XVideo output to become washed out.

To illustrate:
1. Fresh start -> first totem invocation
   Name: XV_COLORKEY
- Current value: 66046
+ Current value: 66051
   Name: XV_BRIGHTNESS
    Flags: XvGettable XvSettable
- Current value: 0
+ Current value: -1
   Name: XV_CONTRAST
- Current value: 128
+ Current value: 126
   Name: XV_SATURATION
- Current value: 512
+ Current value: 509

2. Fresh start -> second totem invocation
   Name: XV_COLORKEY
- Current value: 66046
+ Current value: 66051
   Name: XV_BRIGHTNESS
- Current value: 0
+ Current value: -2
   Name: XV_CONTRAST
- Current value: 128
+ Current value: 124
   Name: XV_SATURATION
- Current value: 512
+ Current value: 506

Etc.
