I use a professional Blu Ray recording deck to save a lot of old Hi8 videotape and mini-dv tape raw footage to create a safe backup for the footage. I guess there is no facility to play the Blu Ray disc manually and record various parts of it into Premiere Elements? I suppose I will have to rip parts of the Blu Ray or the whole thing into the computer as an MPEG4 and then edit that footage.
Each Blu Ray has several individual files at 20 to 30 minutes. I will use Handbrake to encode the files to MPEG4 on the desktop, then break the long segments into smaller clips as individual shots. It will be tedious, but I guess there is no easier way.
Guessing you made bluray data disks and not bluray video disks.
I store raw footage on bd disk also.
Just copy the content to hdd and import into Elements
Old hi8 and dv should import without any problem on a windows machine (dont know mac) as its dv-avi?
