There are a number of possible solutions to this problem, and the right solution depends greatly on what software is actually causing the problem. Some of the most well-known problem causing softwares are DivX and Nero, but there are others that cause the problem as well.
Possible Solutions
• If you are using DivX, you should be upgraded to the very latest version (6.5+)
• If you are using Nero, you can try upgrading to the latest version (7.7.5.1+)
• If you’ve upgraded Nero and Divx and still have the problem, you can try renaming the file C:\Program Files\Common Files\Ahead\DSFilter\NeVideo.ax to NeVideo.ax.bak. You may also need to rename NeVideoHD.ax to NeVideoHD.bak
This will break Nero Showtime, however. (thanks to dugi in the comments for this one)
• You can disable Thumbnail previews, which should make the problem go away, but isn’t the optimal solution.
• The older ffdshow codec pack has been known to cause some problems. The ffdshow tryouts codec pack seems to work better. Might want to try using this one: http://ffdshow-tryout.sourceforge.net/
• If you’d like to uninstall Nero entirely, there is a utility that they provide to help with complete uninstall that helps a lot in instances where you have a bad installation of an older version. http://www.nero.com/nero7/eng/FAQs_Nero7_NeroVision.html
• Some users have recommended installing the Vista Codec Package in order to update all your codecs to the correct versions. I can’t confirm that this works because I have not tried it myself. As always, be careful when installing unknown components and create a restore point.
• You can use the very useful MMCompView free utility from Nirsoft to disable any codecs on the system. This is very useful to help troubleshoot exactly which component is causing the problem.
• There’s another possible solution below of turning off DEP for dllhost, which might not work for everybody. You may have to add divx+nero executables to the DEP ignore list.

Alan McC wrote in with this fix that might solve the problem in a much easier way. Essentially, turning off Data Execution Prevention on dllhost (the COM surrogate) can fix this problem for some people. This solution is detailed below.
Right click on Computer, and choose Properties

Click on Advanced System Settings, and then under Advanced, click Settings

Select the “Data Execution Protection” tab, and then click “Turn on DEP for all programs and services except those I select?

Click on the Add button, and then browse to C:\Windows\System32\dllhost.exe as shown

Click Open, and then OK.
Here’s what you should see…

Now you can browse video folders without problems!

Usually what is happening is one or more applications is hanging up to 20 seconds (in the Registry all values are set to milliseconds) while the OS tries to shutdown. Before making any changes to the Registry it is highly advisable to create a backup.

The first thing we need to do is access the Registry by going to Start \ Run and type in “regedit” (no quotes) then click OK.

Now with the Registry Editor open the first change we want to make is under HKEY_CURRENT_USER \ Control Panel \ Desktop scroll down to HungAppTimeout and change the default 5000 to 1000 then click OK.

Then scroll down to WaitToKillAppTimeout from 20000 to 1000 then click OK. Keep the Registry Editor open as we have 3 more values to change in two different sections.

Next we are going to HKEY_LOCAL_MACHINE \ System \ CurrentControlSet \ Control and double click on WaitToKillServiceTimeout to 1000 then click OK.

Finally, we need to navigate to HKEY_USERS \ DEFAULT \ Control Panel \ Desktop and change HungAppTimeout to 1000 and click OK.

Then scroll down to WaitToKillAppTimeout to 1000 and click OK.

While I am showing much lower timeout times in this post you might want to start with say 20000 to 10000 as some programs may be performing cleanup maintenance. No matter what you change the values to, make sure they are uniform throughout each setting.

The method we are going to use is by creating a batch file to defragment all of the drives, one after the other.

The disk defrag utility in Windows XP can be triggered from the command line with the following syntax:

First, we’ll create a file named defragall.bat, and place it anywhere you like, as long as you’ll remember where it is. If you want to run it from the command line, you could place it in the \windows directory so that it will be available in the system path.

For each hard drive, add a line to the batch file. For instance, if we want to defragment drives C:, and D: we will add these three lines:

defrag c: -f
defrag d: -f

To run the defrag, just either double-click on the batch file or start it from the command line.

. : : HAVE A NICE TRY : : .

Ok now, first go to Group Policy setting, go to Start Menu \ Run and type in:

gpedit.msc

You will see the Group Policy window. You should select Administrative Templates \ System in the tree view:

You will see an item in the right side pane called “Turn off Autoplay”

Double click the item, and set the radio button to Enabled, and change the “Turn off Autoplay on” to All Drives.

Now you should be safe from the autoplay monster.

What a good question.

First, open youtube from your favorite browser (we recommend you to use firefox), and search movies that you want to download.

Now, open a new tab / window from your browser, and go to Here

Don’t worry about your money, because it’s free.

Copy address of your youtube video and paste it.

Then click “Get Video”, and wait for a moment.

Now you’ll see some options, click one of them (we recommended you to choose “Get FLV”), give name and save it to your hard drive.

Note : give extension “.flv” for file that you’ve downloaded.

YouTube: 100 Million Videos Strong

Youtube was created by three pals from PayPal - Chad Hurley, Steve Chen and Jawed Karim - who raised $3.5 million in venture capital to debut their open exchange video site in November 2005. Less than a year later, Google bought YouTube for $1.65 billion. Can you say “cha ching?”
The concept is brilliantly simple. People post videos on YouTube and watch and comment on the videos others have posted. The videos can be anything from a simple rant into a cell phone camera by a frustrated teenager to a favorite sports clip Tivo’d off of ESPN - and everything in between. The numbers generated by YouTube are staggering. One hundred million videos are on the YouTube servers, with 65,000 new ones uploaded every day. They’re watched by 20 million viewers a month.
The simplicity of the technology has aided its popularity. YouTube uses the popular Macromedia FlashPlayer 7 and the Sorenson Spark H.263 codec - which offers the combined quality of Windows Media Player and Apple’s QuickTime without the need to download additional browser plug-ins. In simpler terms, you click and the video plays… period.

The YouTube Community

Youtube is a true global community - with numerous user groups and contests to encourage users to create their own videos, reachable through the “Community” button on any page. The contests might focus on ways to spend a tax refund, telling your darkest secrets, or creating a new music video and some have large cash prizes.
Youtube discourages users from downloading videos to their own computers, preferring that they watch videos online. However, you may embed videos in your own website. Copy the code from the embed box found under “About this Video” on the right while the video is playing. Copy the code, then paste it into your website or blog to embed it.
There are a number of other video sharing sites - including Google Video, UnCut Video on AOL, Vimeo, EyeSpot and VideoEgg. < target=”_blank” a href=”http://revver.com/”>Revver is a popular choice for video producers who want to explore ways to earn money for their work. Video on the web is growing exponentially, but so far nothing can match the cultural impact or enormous volume of YouTube.

There’s a quick and easy fix for this problem. Open up regedit.exe by using Start\Run and then browse down to this registry key:

HKEY_CLASSES_ROOT\Directory\shell

Double-click on the default value and set it to “none” without the quotes, as seen here:

This will restore the normal behavior.
Update
If you are also experiencing this problem when you try to click on a drive, you can run this command from the run box or command prompt:
(Start ? Run ? cmd)

regsvr32 /i shell32.dll

This should restore the normal behavior.
If you are getting a message that says “Windows cannot find ‘PET32.exe’”, then at some point you had a virus, or still have a virus. First, make sure that you run a virus scanner to get rid of the virus. Then run the regsvr32 command above, which should fix the problem.

Follow the given steps to add new destinations to Send To lists:
First click on Start button and type sendto in Run option then press Ok button.

A window will appear with default Send To lists (Compressed (zipped) Folder, Desktop (create shortcut), Mail Recipient, My Documents).

Now using drag-and-drop technique (or using copy and paste method), you can move any program, folders and drives shortcuts to this folder.

Now you can verify, your new shortcut is created in Send To menu.

But next times, if you want to delete any destination, then open the Sent To folder and remove the destination shortcut.
