How can u write a 770MB .avi, 99 minute file to a 700MB Cd?

U can use KGB Archiver to compress (compress it in .rar format) about 1GB file into about 10MB but it will take about 6hrs. but will take few minutes to decompress. BUT if u want to write it without compressing then u can use like Aurora Media Workshop to decrease quality or converting it into an another (Low Size) format and then burn it.
