I have a DCR-TRV 480 cam. Lost the original CD-ROM driver that came with it. (Picture Package V. 1.5) Wanting to transfer videos to my laptop. My laptop does not recognize my cam. Says hardware not found. Running Windows 7 32 bit OS. Wanting to download Picture Motion Browser but it says I need the part number from the original CD. How can I download PMB without the number? Will PMB allow my laptop to recognize my cam? Any help is appreciated. Thanks.
