I eventually bought a external SATA drive. Samsung SpinPoint 250GB, 7200RPM and a Vantec NexStar enclosure. I’ll let you know if I have problems. Thanks for the advice
After some research it turns out that the Panasonic DVX camera do not have a 16:9 CCD (the HDVX do) and so do not shoot true 16:9 without the anamorphic lens. My mistake. Thanks for all the help.
All was captured with Premiere Pro and no manual aspect changes to my knowledge.
Opened a new 4:3 project and all the footage fits – so it must have captured as 4:3 but why?
Is it because I have captured using a different DV device?
