Tony--
It doesn't matter as to DV-R or RW impacting your ISO burn. There is debate
aplenty on + or - and theoretically, plus DVDs have an edge but many people
I know who burn in volume for a living tell me it should not matter. This is
one of the better articles I've seen on that controversy if you enjoy a
little wave physics:

The concept Colin is referencing on upper and lower filter values in the
registry is an important one, but it's not impacting your situation. When
the optical drive isn't recognized, there can be a number of reasons and
MSFT has about 5 MSKBs on remedies, including some specific to certain
software, but the most common situation is corrected by this MSKB--but
that's not in play here. That MSKB is:
CD-ROM drive or DVD-ROM drive appears to be missing after you install
Windows XP
http://support.microsoft.com/kb/320553/en-us
Software in someone's equation can confer those upper and lower filter
values into the registry and block the optical drives from being recognized
in the situation Colin was referencing.
Along with Colin, I would urge you to reburn again. You haven't done
anything wrong--it sounds like you've done a lot right. But sometimes for
unexplainable reasons a burn will work and there are times when it won't. I
also urge you to use a CRC checking utility available from MSFT for Beta 2 I
pulled off of one of their sites:
Reburn Option:
1) Burn slowly. 4X should be fine. Some of this probably varies with the
DVD writer
and the media.
2) Make sure to select an ISO tab if there is one on the burning software,
and make sure to close the session on the burn.
3) Try this tweak on your Windows XP drive and burn from there:
Get to Dev Manager by typing devmgmt.msc in run/win key + pause break or
Rt.click My Computer>Prop>hardware tab>Device Manager if you like 5 steps
instead of one cmd. If you're set to PMI here change to DMO and if set to
DMO change to PMI using these 5 steps:
1) Click the + in front of IDE ATA/ATAPI Controllers
2) Double Click the Secondary IDE Controller
3) Click Advanced Settings
4) Under Device 1 Next to Transfer Mode choose DMA (or vise versa)>Click
OK
5) Reboot your System
6) Check your burn with a CRC utility and the links for this are below
including the direct Taco Bell link. It is very classy, sophisticated, and
very Wagner Edstrom/McCann Ericson esque for MSFT to adopt a Taco Bell url
for their public Beta 2 CRC checker. *Rock on Redmond Rednecks.*
Obtain CRC Utility for Vista Beta 2 Here: (The CRC utility is a way to check
the integrity of the ISO Burn which is probably where your problem
lies--it's #1 on the list):
Here's a link:
The CRC utility for Beta 2 is contained here (Scroll down to the bottom
under "Additional Information"
Microsoft® Windows® Software Development Kit (SDK) for Beta 2 of Windows
Vista and WinFX Runtime Components
http://www.microsoft.com/downloads/...73-F5EA-4B7B-B022-97755838DB94&displaylang=en
Additional Information:
To verify that your download of an ISO file for the Windows SDK Beta 2 build
is not corrupt, download the CRC Utility. (Note: this is not a Microsoft
application. Use at your own risk.)
To run the CRC test, open a command prompt and run the utility. providing it
the name of the file (i.e. crc
c:\6.0.5383.1.1.WindowsSDK_Vista_idw.DVD.Rel.img) The CRC utility will run
two tests on the ISO: it will verify if the ISO is valid, and it will give
the AutoCRC signature for the file. The AutoCRC signature for the Windows
SDK Beta 2 ISO is 0x28434EEF. You should also confirm the size of the ISO is
correct: 1.14 GB (1,229,355,008 bytes).
If it fails any of these three tests, re-download the ISO.
I really like the direct link to it though if you right click CRC here>left
click Properties:
