I edit in Premiere Elements 7 or Adobe CS3 and with both we have the same output to camera problems as above. However, PROBLEM SOLVED! I also have Magix Edit Pro 14 which is very slow for editing HD footage so I use Premiere. However I import my finished (edited) Hd footage onto a Magix timeline then Export to my HV10 with no problem.
I belong to a film making group who between us have 6 HV10s and know that this problem appears to be specific to Canon as I've not come across the same problem, exporting from the same programmes to Sony cameras.
