Why is the "time remaining" in the DVD burning process so far off?

I've used every Pro-sumer video editing program out there, and I have settled on PD10 as my program of choice; it tends to do most things better.

However, one thing that is one of those trivial issues that nonetheless drives me crazy is the inaccuracy of the "time left" estimate when burning a DVD. It seems to always display FAR more time left than is actually required. A typical example: as I am typing this, I am authoring and burning a DVD. About 4600 MB of movie. It has been authoring for about an hour (yeah, time for a new notebook!) and it is 71% done. Yet the time left being displayed is 1:51:57. I know that it will only take about 20-30 minutes more to author the movie, then a very short time to burn it. This time estimate has absolutely no basis in any kind of reality. It also displayed the time left, when I looked about 40 minutes ago, as about 1:49:33.

Is the algorithm that the program uses for this just completely broken?

Addendum for illustration: 96% done and it shows that there is 1:41:22 left. Argh

Hi DocDaddy

I've often wondered this too!

I believe it is a PC thing.

I use a Mac as well and when you copy and paste or write a DVD it just does it! No silly time remaining and a graphic file transferring imaginary 'stuff'.

Happing editing

Hi DocDaddy,
It is my theory that the way bits and bytes calculate now differs it used to be 1024byte for KB, 1024KB=Megabyte,1024Mb=terabyte. But in last few years it has been dropped to 1000byte=KB, 1000KB=MB, and 1000MB-terabyte, so calculating of sizes varies as the which ## the program uses.
This is my own thoughts, not based on fact.

DocDaddy,

It is a known fact the PDs estimate of the disk size has nearly always been crazy wrong.

The amount the estimate is off is somewhat dependant on the type of videos you have on the timeline with AVI the worst offender.

If you have MPG2 files on the timeline, the estimate is closer.
