If your Sony is a miniDV HDV camcorder, then be advised that Premiere Elements 13 does not have the DV and HDV data capture firewire into Premiere Elements Capture Window.
The last version of Premiere Elements to include that featuer is 12/12.1.
Adobe has a document describing suggested workarounds for the Premiere Elements 13/13.1 situation.
Please review and consider.
