7.6 volume craziness

Question

So after installing I went to my favorite internet radio station to play some on demand sets. When the stream is playing the volume appears to randomly self adjust up and down. There doesn't seem to be a pattern to this at all. I have played the first 20 minutes or so of this stream 4 times and the volume shifts happen at different points in playback for different lengths of time.
I didn't change any settings in preferences before or after upgrading. ( sound check is unchecked ).
I recorded the stream with Audio Hijack Pro, playback did not have any volume shifts and sounded just fine
I also noticed, when iTunes is in compact mode, a mouse passover now causes the volume button on the slider to shake back and forth rapidly until the mouse is not over the app any more.

+Error writing to the file: C:\Program Files\iTunes\iTunesMiniPlayer.Resources\nb.lproj\iTunesMiniPlayerLocalized.dll. Verify that you have access to that directory.+
More often than not, that sort of message indicates file damage rather than a privileges issue on the file.
If you've got Windows XP, try doing a chkdsk over your C drive, as per:
How to perform disk error checking in Windows XP
If you've got Vista, try the following procedure. Go "Start > Computer". Right-click on "Local Disk C:" and select "properties". Click the "Tools" tab. Click the "Check now" button in the "Error correction" section.
Do the disk checks find/repair any damage? If so, does an install go through properly afterwards?
