SHERLOCK - The Codec Detective

SHERLOCK - The Codec Detective



Having Trouble with Video and Audio on Windows XP?  

We *ALL* have problems with Video and Audio files from time to time...even Digital Media professionals like myself!

One of the biggest causes of this type of problem is "CODECS".

(NB - If you are not familiar with the term codecs you might want to read my article on Codecs and WMP for background information)

Audio and Video playback problems can often be caused by NOT having the correct codec installed on your computer, or even the wrong version installed...

I, and many other Microsoft MVP's help other users online, by troubleshooting their media related problems via the newsgroups such as the Microsoft Windows Media newsgroup.

Now when we ask the person what codec's they have on their computer 99% of home users do NOT know...

For example:

...if you are using Windows Media Player 9, 10 or 11 to watch DVD's on your computer using the low cost and Microsoft approved plug-in:

The CyberLink or COREL DVD "WMP Plugin"

... do YOU know what codec is being used to play back the movie on your computer screen???

For the average home user finding this information was very difficult - UNTIL now that is!

I noticed that there was no reliable utility that could:

# Determine the codecs installed on a Windows XP computer

# Check to see if any of the codec's were "BROKEN" (will be highlighted in RED....)

# Export the data to a text file for technical support!

# Was FAST to run on a PC and did NOT require installing...

# SMALL enough for download by modem!

...So I created one!

I call it:

SHERLOCK - The Codec Detective

The important thing to remember here is that YOU do NOT need to understand what this software DOES!

You just RUN it, click the SAVE button and it CREATES the TEXT file automatically...

All YOU do then is email the file OR "copy and paste" the contents of the file to whoever is providing you with technical support!

Couldn't be easier!

More Information: 

The software is extremely small in size at 80Kb AND does NOT install itself onto your computer!
Just download it and place it in a folder. When you require it just double click the file sherlock.exe and it will run - SIMPLE AS THAT...




It is designed for Windows XP Home Edition & Windows XP Professional ONLY (but does work on Windows Vista)

This is a free utility and I offer NO SUPPORT
