i have a short mpeg file that i am using as a test to see whats the best possible quality i can get on a cd if i am trying to get 45min on the disk. its a 1 min clip and the file size is 15 megs. if i have done my math correctly 15 megs times 45 min = 675. so when i load it up on nero as a non-standard vcd it is taking more than 1 min worth of space on the disk. its more like 3 min. but if i choose to re-encode it and make it a standard complient vcd then it is down to 1 min. what does the re-encoding do to the file? and why is this 15 meg file showing up as if it were 45 megs??thanks
