HJTSM? I missed that one!I was able to FTP a SD and HD file group (TS, NTS, HJM, HJTSM) to my pc, where I did as you suggested, but was unable to return them to their previous location in the 'Recordings' folder, as I got the all to familiar 'Operation not permitted'. I was permitted to FTP them to the 'Downloads' folder, then found that I could move it to the 'Videos' folder, but this only moved the TS file, the NTS, HJM, & HJTSM files remained in the 'Downloads' folder.
Sounds like the whole idea is completely busted!
Sorry for wasting everyones time!
