Why does Virtual PC/Virtual Server have a 2.2 GB limit on virtual DVDs? Update: It doesn't support Virtual DVDs
I'm going to go ahead and ask a stupid question... Why does Virtual PC/Virtual Server have a 2.2 GB limit on DVDs?
All the VS.NET downloads are on DVD, and the program that is perfect for testing them on, can't natively handle them. I know there are work arounds, but you'd think that after a year or more of having the product, someone in MSDN would go over to the Virtual PC/Virtual Server group and tell them to fix the issue <grin> Or at least build one of the work arounds in, so it's seamless.
Update: (12/31/2004) From Ben Armstrong (Program Manager for Virtual PC)
Unfortunately we do not really support DVD images at all. We only support the CD ISO image format. It turns out that this format can support up to 2.2GB. In order to support higher we will need to add native DVD image support – and we have not yet done that. It has only been recently that people have actually started using ISO images that are over 2.2GB in size.
So, it's not a case of the system being able to handle regular to large DVDs, it's that it really doesn't handle DVD's at all, and it just works with small ISOs of some DVDs.
Of course, it would be nice if the program told you this when you tried to mount a large ISO <grin>
