Thanks for the suggestion. I don’t think it can be this as its a new drive with plenty of space. Also I took it along to another facility and tried ingesting using FCP 7. No problem worked quickly and simply.
My conclusion is that FCP 5.1.4 can not handle the G20 recorder for some reason.
As a work around for now I have ingested the files through FCP 7 using another project name even though I can not run the FCP 7 project on my machine with FCP 5.1.4. However as FCP makes the files into .mov files I was able to drag these into the 5.1.4 project with no problems and everything runs fine. I think this is because FCP does all the work in Quicktime. As I have the latest version of this it does not seem to be a problem handling these movs. Not an ideal solution but one that gets me out of jail for now.
