Does DVD-A support 2x burning speeds

I burned my first DVD using Architect. All went well, but I could not get Architect to recognize the 2x TDK disks that I was using (DVD-R) DVD-it Pro recognizes these same disks and burns at 2x speed. I notice, too, that the drop down menu in DVD-A only has a 1x speed choice. Is 2x burning something that is to be added or what...?

Depends on the drive firmware I would think. I have a HP 200i which supports 2.4X burn speedand it runs fine at that speed. The one little thing I noticed is when you first insert the blank DVD disc it shows a different speed, but once it spins up, it shows the correct 2.4X speed and burns at that rate at least on my system. :-)

For those new to burning DVD's, their speed scale is very different that the speed scale for CD's. A 2.4X DVD drive is about roughly the same at 24X CD if I remember right.

Well, it showed 1x and burned at that time - roughly realtime (hour movie - hour burn). Now that was a 2x disk and should have burned in the half the time - that was my experience with DVDit Pro - (hour movie - half hour burn).

I wasn't aware of the speed scale you mentioned, but if that were the fact shouldn't a 2x speed disk burn in 1/24th the time of 1x? I'm confused by what you said.

What has me confused is that I have only burned a couple of very short projects in DVDA. I have used DVD Workshop to burn projects that were over an hour long. Seemed to burn at 1X. However in DVDA a 30 second spot with a main menu, sub menu and scene selection menu took 14 minutes to burn. Burning lead in about 2 minutes, tracks about 30 seconds and burning lead out 11-12 minutes. Is the lead in and lead out time something you have to tack on every burn no matter how long the video material is? Just for drill I tried the same 30 second spot in movie mode with no menus and still took 1 minute for lead in, 30 seconds for tracks, and 12 minutes and 30 seconds for lead out.

I think DVD-A does this on purpose to make sure the disc is 100% compatiable;
AFAIK there needs to be at least 1GB on the disc to make it compliant...?
