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. So, if you want to run it on any PC with Vista or Windows 7, that PC will not recognize the camera.
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). Being out of warranty, it's $141.00 flat rate to ship out and get repaired. This is inexcusable to have the same kind of problem within 5 years on two different Sony products. Never again.
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. If you buy Sony, you better get the extended warranty. Dealers won't stand behind what they sell if it's out of warranty. They know it's junk. I have learned my lesson. No more Sony products.
