Dont worry, its quick: single layer disc 4.7gb so i should burn only 4.3gb... What is the target filesize for a DL disc?
By using DVDShrink you can fit more than the 4.7g for a DL it's around 9g., but once again using Shrink you can exceed that.
A single layer (dvd-5) holds up to 4.38 gig - a dual layer (dvd-9) will hold 7.95 gig. You can lower your target size in Shrink so that you don't burn to the edge of the disc.
@binkie7, well I learn things every day, I thought DL held 9g, hence calling it DVD9 @limelight, sorry for the wrong info, now I feel embarrased.
No need to feel embarrassed - it's deceiving. They calculate w/ 1000 mbs to a gig when for computers it's really 1024 mb per gig.
But for a couple of your concerns, there is one thing I would like to point out. The DVD size is based on a 1000 based system rather then 1024 (which is the true size system) I do not agree personally that DVDs should be labeled 4.7GB, as they only truely hole 4.36GB. Let me do some math for you to explain a little better. 1000 based system 1000bytes/1Kb 1000Kb/1Mb 1000Mb/1Gb so according to this system the DVD should have 4.7 Billion bytes of information. Now lets take that number and put it into the true size specifications 1024bytes/1Kb 1024Kb/1MB 1024MB/1GB so 1024³x4.7 this is equal to 5046586572.8 bytes but a dvd only holds 4.7 billion bytes, so we work out 4,700,000,000 / 1024³ = 4.37.........ect now count in lead in/out and minus about .01GB for that, So by true size specifications, the accual amount of data that can be held onto a DVD is 4.36GB with lead in and out (for compatibility).
@ireland, thats exactly what I thought. You could have shown some pics on how you worked it out though, Cheers
So to confirm, the target filesize for DL discs so that there wont be any audio/video sync errors is 7.9gb correct?
Give or take a meg to compensate for the lead in/lead out as ireland pointed out. The the program you are using will know the target size & the max amount that can written. Just pick which you will be using DVD-5 or DVD-9. The audio/video sync sounds like another problem. Are you converting like .avi's etc or making backups of original dvd's? edit: spelling
The audio sync problem can be media and/or burn speed. Which media gave you this problem? What program did you use?
No issues, but simply put: single sided dvd+r: 4.7gb(advertised), actual burning capacity->4.3gb. Double sided DVD+DL: 8.5gb(advertised), actual burning capacity->?????
