thanks, so i'll try to remove and reinstall wintv applications.
I've noticed another problem that maybe due to the same system configuration.
When i go into RR mixer (skin BMV2), there is no change in winamp equalizer when i click on RR presets (rock, rap, pop....) and even no change in RR equalizer.
On the other way, when i load a preset in winamp, the equalizer in RR mixer is changing correctly to be the same as winamp equalizer.
Have you got an idea ???
My version of winamp is a 2.78c
my OS is windows XP pro SP2.
