You actually need to Update the BROWSER itself. You are running an out of date version of Internet Explorer. You log shows you are still running IE 6. IE 8 has all ready been released, though I would advise against installing that. But DO update to IE 7 this could possibly part of your updating problems or viewing YouTube videos. IE 7 is perfectly fine, works well, all the bugs are out. Leave IE 8 alone however, too many are having problems with it.

After having read posts 8 and 9 I came to the conclusion that the files in question are playlists. If that is indeed the case then it's normal behavior and that they would normally just be hidden.
