Exporting video onto CD and DVD.
Process: -
On Adobe Premier 6.0, click file export timeline, then movie. From there give a name and then click setting to change the codec compression, type such as quicktime microsoft avi etc. Then click next to change the other settings. Click ok and then it makes the file.
I did some research on the different types of compression, using codecs, the process of encoding and decoding. I used the following sites to make my decision on the type of ones to use: -

The main options i have is to create a Quicktime file format. It has a low compression ratio (2:1). It requires not hardware and keeps lossless compression. Due to the fact that it has low compression, means it needs a large capacity in order to store it, and also due to this needs speed, in which case its not ideal for a CD but could be fine to use on a DVD.
MPEG-1 which was released in 1993 (Moving Picture Experts Group) was a standard way of compressing video. It being very popular and also windows comes with a MPEG-1 decoder as standard. Its used for video on CDs and also easy to convert, which maes t a good one to use for the CD if the option is there.
MPEG-2 is also popular, used for high quality video in which would be very useful to use for videos on DVD, another option to use.
Also i have been told a different way of doing this. As it has to play on the university machines, why not be sure that it will play. I will create different coypies, but i have been told by a friend that leaving it uncompressed when exporting, downloading Windows Media Encoder 7.0, and then encode the file that was created using this software. This create a Windows Media Video file and then it can be played on any machine that has Windows Media Player, and as it comes standard with Windows, it should work.
I tried exporting the file this way. It was over 400MB, and using the Windows encoder, it compressed it down to just over 4MB, so there is a big difference. Not much Quailty has been lost when watching it, the sound is fine and will work fine on a DVD. I also tried it on a CD and ran straight of the disk fine with no problems and therefore looks fine. However to be on the safe side, i will create a second one which will have lower pixels and frames per seconds so that it diffiniatly work.
So i will try the different codecs, mainly the ones i have explained. I don't think i will use the codecs such as Xvid etc as these are not established on every machine and may reqired to be downloaded of the interent and therefore not be suitable for this project.
Final Codecs used.
Microsoft DV AVI
Microsoft DV AVI (changed the pixels and the FPS for CD)
Quicktime - Two different compressors for CD and DVD.
Uncompressed - Compressed using Windows Media Encoder series 9.
I did four different copies for each DVD and CD and placed them all on the disk, so that it will work if the file falls corrupt or doesn't work for some reason.
