Could someone please post a screenshot of these flash ads?

For now, try the following (I'll probably get shot for this, but hey)
For Win2k/XP/2003, go to: "c:\windows\system32\drivers\etc" folder
and open the file "hosts" (no extension) in Notepad (eg. rt-click > send to/open-with > notepad)
Or you can use eg. HijackThis > Misc Tools > Hosts File Manager > Open in Notepad
Add the following line (under "code") and save (copy & paste from here)
This will remap the ad site used on winamp.com to your localhost,
resulting in the ads not being found, and therefore they can't be shown.
Note that I tried removing that entry from my hosts file, restarting winamp, but I still don't see any ads in Online Services > Shoutcast Radio. I also looked in Shoutcast TV, Winamp Music, AOL Videos, and didn't see any ads there either (sorry, I don't bother with any of the other ones, though it wouldn't surprise me if there's ads in Winamp Remote, MusicNow, In2TV, Games - though I'm not even gonna bother enabling them to find out).
Maybe it's because I've also got *.doubleclick.net in the Restricted Sites zone in Internet Explorer > Options > Security? I've had doubleclick.net in there for years (automatically added by one of Spybot SD or SpywareBlaster).
Note, the ad sever may be different for other countries.
But you know how to look in the Internet Explorer cache (Temporary Internet Files folder) and open/search the html in Notepad, yes?
