When I try to use the capture mode in Sony Vegas Movie Studio trial version, I get an error message: Xvidcore.dll, and I'm unable to capture video from my camcorder. I've had this error for some time, but I ignored it as my other program, WinDVD, was able to still capture video (With some coaxing, albeit.).
I've never used the Sony Capture Mode. Instead, I use a free program called HDVSplit to transfer the raw footage onto my computer. The program will even automatically split the scenes for you. I have Sony Vegas access only the computer files during the editing.
