Summary: On the product site it says, "...camcorder may not be recognized by the computer when connected. In this case, check to see if there is an updated driver available for your model." There are no device driver updates available for this camcorder beyond XP.
Summary: I bought the TRV480 a little over a year ago and once again started getting the C:31:22 and C:21:00 errors same as I had gotten on my previous Hi8 TRV120. Apparently, a problem with the moisture sensor (I live in dry, non-humid California).
Summary: Great features and great technology but as usual with Sony, it's junk. Sony products just don't last. I had mine for one year. Needs video head now. 264 dollars to repair. Previous Sony camcorder stopped ejecting tapes after one year. 185 dollars to repair.
