Yeah I got a TRV25E; Windows 98SE. When I first got the camera Everything worked fine first tiime Installed USB drivers and It was all good. Now I install USB drivers. And I can only stream video and audio from the damn camera. I cant access the memory stick at all. If I turn the camera on to Memory my PC crashes; untill I turn the camera off then the PC brings up the Removable Disk icon in Explorer but since the camera is off the icon disappears after a split second. This is really annoying. And SONY have been no help whatsoever. I asked them for a link to an updated driver and they sent me an email back with the text "http://www.sony.com/ - This is where you will find all the updated drivers". Or words to that effect. Anyways Check out(posted 7736 days ago)http://www.usb-drivers.com/companies/965.htm
You should find updated drivers for the MAC here. Good Luck
