Yes it is Picture Motion Browser along with the manual and registration links.
I googled and could only find the software for sale even on the Sony site,I seem to remember lots of people trying to get this software from Sony for free but without any luck.
The editing capabilities of Picture Motion Browser is very basic,I have the same camera and I use adobe Premiere Elements 4 which is excellent,but there are lots of video editing programs out there,depends how much you want to do and how much you want to pay.
Sorry I can't be of more help.
