Windows 7 can semi-handle .mp4's natively with the newer version of WMM what works on Win7, but XP and the old WMM cannot.
Saiid, I did get Quicktime Pro because it would let me break up a .mp4 without degredation into smaller files I could work with.
You can edit .mp4 in XP with Adobe Premier Elements (may require a correctly installed codec pack), but the real truth is you have to have a newer computer with some horsepower. My old Pentium 4 machine can't handle it; duo-core a must and quad-core better. I'm still trying to find a good method too.
