Yes.  It appears Sony have got work to do here.

The reset/series option in camera Settings DOES NOT WORK.

The only option is to manually batch rename videos and photos immediately after downloading them from the card.

This is totally lame, Sony.

This camcorder cost a lot of money and i expected better.  Even my panasonic compact camera remembers imsge filenames and continues the in use sequence, irrespective of formatting of sd cards.

Lame!
