Hey Steve,
Yes … I have … AARGH#@$%^!.
You need to go to the web site of the makers of P2log pro.
https://www.imagineproducts.com/dlupdates.htm
They have a utility that corrects those invalid files. It is called “repair tool” demo and it can be found at the bottom of the page that I have given you a link to. You can download the free trial or “demo” version, which will allow you to fix files one by one … or a full version which will fix whole folders of these invalid QT files.
The problem is that you used QT 7.2.x or earlier along with P2 Log pro when you unwrapped the raw P2 data. QT 7.3 and later versions will now not play those QT files.
I think Imagine Products should provide the utility fix for free, but if you have time, you can repair the files one by one with the trial version.
Hope this helps you out Steve.
Peter
