How about trying this:
1. Start > Control Panel > Network Connections.
2. Double click on your network.
3. Under [b]This connection uses the following items, select Internet Protocol (TCP/IP). Click on Properties.
4. Select Use the following DNS servers.
5. Type in the following IP addresses:
165.21.83.88
165.21.100.88
6. Click OK twice to apply the settings.
You will also need to set a static IP address in order to use the DNS server option.
Usually the address is 192.168.1.X
Gateway is 192.168.1.1
Subnet mask is 255.255.255.0
If you are unsure, do this:
1. Start > Run and type in cmd and press Enter.
2. Type in ipconfig and press Enter.
Enter the details as what ipconfig tells you.[/b]
The term codec is also an acronym that stands for "compression/decompression." A codec is an algorithm, or specialized computer program, that reduces the number of bytes consumed by large files and programs.http://searchnetworking.techtarget.com/sDefinition/0,,sid7_gci211810,00.html
In order to minimize the amount of storage space required for a complicated file, such as a video, compression is used. Compression works by eliminating redundancies in data. Compression can be done for any kind of file, including text, programs, images, audio, video, and virtual reality (VR). Compression can reduce the size of a file by a factor of 100 or more in some cases. For example, a 15-megabyte video might be reduced to 150 kilobytes. The uncompressed file would be far too large to download from the Web in a reasonable length of time, but the compressed file could usually be downloaded in a few seconds. For viewing, a decompression algorithm, which "undoes" the compression, would have to be used.
There are numerous standard codec schemes. Some are used mainly to minimize file transfer time, and are employed on the Internet. Others are intended to maximize the data that can be stored in a given amount of disk space, or on a CD-ROM.
Codecs are used in many popular Internet products, including QuickTime, Netmeeting, Cu-Seeme, and VDOphone.
