Last Sunday I started working on some wedding video editing and transfer to DVD for a friend. Right after I finished rendering the first 1.5Gig MPEG I noticed Windows Explorer using 100% of the CPU resources for a minute or more when I opened the directory with the large file.
I started playing around and found that all my folders with large AVI or MPEG files caused this problem. The problem was especially bad in one folder that has an 18Gig AVI capture file.
Searching around the net for information on this problem I found a number of forums with people having the same problem. The information led me to a Microsoft Knowledge base article with details about the problem. The culprit is Shmedia.dll analyzing the file contents to let Explorer display media specific information about the file. The Microsoft article states that the problem was fixed in SP2 but, since my PC is fully patched I think the problem has come back. Also the article says the problem is only with AVI files but I was seeing it with MPEG files as well.
There are a few different solutions posted around the net for the AVI problem. Looking at the various solutions I chose to use the CLSID renaming method as detailed at pc-speed-up.com.
As I expected, renaming the CLSID to:
fixed the problem with AVI files but did not help with the MPEG files.
I looked in the registry to find out what CLSID provided the hook to Shmedia.dll for MPEG files. I found that
is the key for MPEG’s. I renamed the key to:
and it fixed the problem for MPEG’s. I hope this helps someone else having this very frustrating Windows problem.
WARNING – manually editing the registry is extremely dangerous if you are not careful you may have to re-install windows to get the PC working again. You have been warned so, don’t complain to me if you screw up your PC by following my information.
In another interesting article from Conformity Magazine’s newsletter, they detail five recent product recalls. When will engineers and manufacturers start taking safety seriously.
In case anyone thinks the FCC isn’t serious about enforcement, Conformity Magazine’s newsletter has this article about a proposed FCC fine of 1 Million dollars against Behringer USA.
I’ve been dealing with FCC emission regulations for coming up on 20 years now and, this action by the FCC reminds me of how important it is to follow the FCC rules no matter how much effort it takes.
I have not had free time to post anything to my blog since before the year end holidays. Between work, the holidays and moving I’ve been swamped. Hopefully I’ll get back to posting soon.
The new version of Firefox has been released. It’s working very well for me. Get your copy today.
Microsoft is giving away Visual Studio Express absolutely free until November 2006! I’ve checked the license agreement and faq and it includes the redistribution license and allows commercial usage.
I haven’t gotten it installed yet but I’ve heard that some of the features of from the professional version are disabled but they are likely features that casual users like me won’t miss.
You can install it from the web or download CD images at the manual installation instructions page.
As reported by EE Times, the Gartner group is predicting a long term decline for the DRAM market. This should be good news for all us PC users who keep needing more and more RAM.
Check out the whole article here.
This article in Conformity magazine points out that 2005 has set the record for most product safety recalls according to the US Consumer Product Safety Commission (CPSC).
There is also an article highlighting the latest recalls.
One item they don’t mention, they probably don’t know, is that at least some of the replacement PS2 AC adaptors have also been recalled. I know this because my brothers adapter was subject to the recall. He promptly received the replacement adapter and, then received a second replacement from Sony because they needed to recall the first replacement, Doh!
With the apparent incompetence on the part of Sony regarding the rootkit DRM (see previous post for details) and now botching the PS2 adapter’s I’m beginning to wonder if Sony is being managed by Homer Simpson. 😉
The inventor of Ethernet, Bob Metcalfe, was interviewed by EE Times this week. As usual, Bob is informative, entertaining and controversial.
I particularly like his thoughts on blogging and the New York times on page three of the interview.
This EETimes.com article summarizes the results of a survey by Industry Directions.
As one who works in electronics and, has been involved in outsourcing, these results are no surprise to me.
