I have Windows XP 64-bit, and am having a some weird issues with a 64-bit build of VirtualDub. In the release notes on SourceForge, it it says that the 64-bit version was compiled specifically for CPUs that support AMD64/x64 long mode. How can I determine if my CPU supports this?

From the VirtualDub site:

This version is compiled specifically for CPUs that support AMD64/x64 long mode, including AMD Athlon 64, AMD Athlon X2, AMD Opteron, Intel Xeon CPUs with EM64-T, and Intel Core i7 CPUs

In essence, all modern 64-bit processors. ("Intel Xeon CPUs with EM64-T" includes Core 2 (Duo), and similar)

I don't have a Core-2 Duo, I have a quad-core. How can I tell if it supports it? – Josh Stodola Dec 30 '09 at 22:51
It does :) Note that you also have to be using the right version of windows. – James Dec 31 '09 at 1:25
How can you be so sure it does? – Josh Stodola Jan 5 '10 at 20:54
It's a Core-2 Quad, right? Well that's the most likely, and they are Xeon based, so support EM64-T. – James Jan 10 '10 at 21:03
