Sony DCR-TRV8 video transfer problems
The USB drive for Sony CAM you can download from Sony web but the USB will not allow you to transfer video from your CAM only for memory stick
However if you have firewire input on your Laptop, have you? normaly if you have firewire input on your laptop as soon as you connect your CAM it will detect automatic either with windown movies maker or with Nero
Sometime the firewire from CAM defect I repaired a few of them with this problem
Can you conect this CAM to another computer or try different cable ?
Or tell me exactly what input you have on your laptop such firewire input, PCMCIA slot
