Since installing Service Pack 1 I have had major problems with video clips. There are a number of scenarios with one thing in common: when I open the folder that contains the video files, the address bar starts to gray out as it loads the file icons then slows drastically and the icon stays as the label (MPEG, WMV, AVI) without the thumbnail picture for none, one, some or all of the files in the folder. Eventually the address bar is totally grayed out but the "label icons" remain "un-thumbnailed". Sometimes when I go to another folder and return to the original folder one or more "label icon" turns into a "thumbnail icons".
All files can be opened and play correctly whether they are "label icons" or "thumbnailed icons".
When I try to delete or move the "thumbnailed icons" everything works perfectly. On the other hand, almost anything except correct operation occurs with "label icons".
For example, when I try to Empty a 16.1 MB "label icon" from the Recycle Bin, I get a box that says "Deleting 1 item (16.1 MB) - From Recycle Bin - 0 items discovered (0 bytes) - under More Information: From: Recycle Bin - Time Remaining: Calculating... - Items Remaining: 1 (16.1 MB) - Speed: 0 bytes/sec" and the progress bar shows a small bar moving across it from left to right but the progress bar never turns into a solid line.
This box never changes and is shown in Task Manager as a Running Application. The only way to absolutely get rid of the box is to end the task using Task Manager. Using the Cancel key or the X to close may or may not close the box.
When I try to move a "label icon" to another location or click delete sometimes it will move to the new location or the Recycle Bin or I get the box described above.
I can only guess that the problem stems from not being able to get the thumbnail information and that the drastically reduced speed of the address bar is a symptom of trying to find the info.
I have done the following:
Tools->Folder Options->View->unchecked Always show icons, never thumbnails
From Brink's tutorial:
(
Thumbnails in Windows Explorer)
2. To Enable Windows Explorer Thumbnails -A) Click on the download button below to download the Enable_Explorer_Thumbnails.reg file.

3. Click on
Save, and save the
.reg file to the
Desktop.
4. Right click the
.reg (On Desktop) file and click
Merge.
5. Click on the
Run button for Security Warning pop-up.
6. Click on
Continue (UAC),
Yes, and then
OK when prompted.
7. When done, you can delete the
.reg file (On Desktop).
8. Logoff and logon, or restart the computer to apply changes.
So far, no joy
Any and all help greatly appreciated as this is driving me crazy (normally a pretty short drive anyway).
