So I have a Panasonic TZ30 and took a short movie clip which I was hoping to load to YouTube. The computer sees a AVCHDTN file which then translates to a TID file which Microsoft wont recognise. If I Google the thing it says my registry is corrupted and needs fixed. I have a registry cleaner and that's been run but has no effect on the file. Panasonic are no help. Any ideas folks please? forgot to add. Windows7 and IE11 and AVG. thanks. .
