It's been a while Jim since I've been here.
Its a Legria HFR18.
They are MTS files.
Funny thing though, in the last hour since I posted I tried to roll back the latest Realtek audio driver I recently updated.
It never "rolled back" and I'm left with some Microsoft Audio but it fixed the problem.
Anyway while I'm on, what spec of machine do you suggest to edit AVCHD files as my machine is very slow and the preview screen stutters a lot in Videowave.
