What computer operating system?
Like 13/13.1, 14 does not have the DV and HDV Data capture firewire into Premiere Elements Capture Window. The last version that has that feature is Premiere Elements 12/12.1. Please refer to the following Adobe document on this matter, including Adobe suggested workarounds for the matter.
Some are now capturing firewire in other programs and then bringing the captures into the Premiere Elements project (Add Media/Files and Folders).
