The device 'Microsof AV/C Tape Subunit Device' could not

be opened.

When I try to capture ticking the DV button versus the HDV

or SDI button, my Sony camera doesn't drop down and I

get this message;-
The device 'Microsof AV/C Tape Subunit Device' could not

be opened.
I used to be able to tag my exact Sony Camera . Would

this only be available when I hit the Capture HDV or SDI

button or is it in my menu on my Sony camera. I can

capture into M2T format this way.....maybe I shouldn't be

so fussy or maybe I can load the driver for DV selection?
