Not enough room on DVD-R

[jedijfo]

Question - I have recorded some movies off satellite directly into MPEG2 using an ATI capture card. The problem is sometimes a 4.2 - 4.3 GB files fits on a DVD-R disk and sometimes it does not... I am using Showbiz to burn the file to DVD-R. Any ideas.? I thought a DVD was 4.7G?? How do I shrink the existing files and keep this from happening again?

thanks,
Jack

Age old problem. This applies to Hard drives as well.
Media manufactures specify 1 kilo byte as 1000 bytes.
Computers are binary machines so 1 KB should be 1042 bytes.
So a DVD-R will write 4.7Gb (decimal system) or 4.3 using binary.
So you only really get 4.3 and you're right on the bondaries with your files, which are correctly reported assuming 1k as 1024 bytes.

Take a look at you 120Gb HDD, it will not be reported as 120 by the Opsys.

It's the difference between a traditional computer Gigabyte and the 'new and improved' Gigabyte.

DVD Shrink will take care of the problem. It will bring the file down to the correct size if you're overbudget.

If the authored DVD turns out too large, use DVD Shrink.

Maybe 1024?

Not if you're dyslexic. :P

Actually, it's a completely different story for HDD, much older than the DVD thing. Advertised HDD capacity is a raw unformatted number of "real" 1024-based gigabytes. The useful capacity is less than advertised due to the overhead for the sector headers, checksum, etc. that's applied during the physical formatting of the HDD. Those who used to have the first MFM HDD models, which required physical formatting, must remember this.

At least checking a file's properties now will yield a number in binary kilobytes, and a number in bytes, so all it takes is a right-click to see if it'll fit on a DVD.
