How do I put videos from my Sony infoLithium Digital Camcorder onto my computer?

I have a sony infoLithium camcorder, and the video I need to transfer to my computer is recorded on a cassete. How do I transfer it from the Camcorder/cassete to the computer so I can eventually upload to youtube?|||u need a dvd recorder to burn your video to a blank dvd. after rip that to your computer. and convert it to the format which u can use. dvd recorder can cost u about $100. good luck . . .
