I shot a couple of rolls of Sony Excellence miniDV tape from a new lot I'd just received from B&H, and on playback both showed intermittent video breakup (horizontal sections perhaps 1/10th of the screen in height, horizontally offset) along with missing audio in those sections. Visual inspection of a bad section shows, looking at the non-oxide side of the tape, a series of pin-point protrusions spaced a few mm apart extending in the direction of tape motion. (The tape is indented as if pushed by a pin from the inside). Did my camera (VX700) suddenly go crazy, or did Sony's tape-making machine go haywire? (I've been using the same tape as my "standard" for quite some time with no problems.) Any suggestions on a house that would take a stab at recovery would be appreciated. I'm in Los Angeles.
