panasonic vdr-m50 camcorder and VRO files

Hi, My panasonic camcorder records to ram discs in a VRO file format which no
other software that i have come acros seems to recognise even the copy of
Sonic my DVD that came with the camera doent recognise the VRO file format
can any one help.

I'am using win XP prof with service pack 2 and p4 2gig prosesor and 640 ram.

one other thing at one time (before service pack 2 ) i could plug the
camera into a usb port and use the camera as a drive but now it just freezes
the comp until i unplug it the the comp returns to normal.

Regard Neil
