Sir, you have saved my life!
If you're looking for drivers, Vista may include it. Or you can click Start, Programs, Windows Updates. Plug the cam in with USB prior to updates.http://www.google.ca/search?hl=en&client=firefox-a&rls=org.mozilla%3Aen-US%3Aofficial&hs=Hrv&q=DCR-TRV255E+driver+vista&btnG=Search&meta=&aq=f&oq=
Sony doesn't list this item anymore.
I downloaded the sony usb driver from one of those sites on the google page that you gave me (i can't remember which one).
Unfortunately it doesnt' work on vista but i do have a second computer which still operates on xp and that worked fine!
I simply installed the usb driver onto the computer and then opened my video camera with windows movie maker. great!
it's a damn shame that vista has so many problems ( i got my vista computer as a gift - unfortunately i can't sell it, because that would be rude but i still have my first computer which i use when vista doesnt work - which is a lot! Microsoft really sucks
good luck to the people with only one computer (vista)
