If you'd have done what forum rule 1) tells you, you might had found out that Win98SE uses FAT32, which is limited to 4 GB for one file. Unfortunately VirtualVcr doesn't support splitting. There two ways to capture longer sessions: Switch to iuVCR, it can split the capture to several files of a maximum size. Upgrade to Windows 2000 or XP. They both use NTFS as file system, which hasn't such a 4 GB limit.
