How can I transfer videos from handycam ccd-trv94e to PC?

You are reffering to VHS tapes which play in a VCR. They are analog so you need a special device to convert the tapes to digital.

They sell video capture cards so you can do this yourself at home but I suggest using a video transfer service for the best quality and least amount of hassle. StashSpace.Com is a good one. Costs $6.95 per tape for the transfer. Check them out online or give them a call.
