I have lots of home videos of grandkids etc would like to put onto computer what do I need to do this - ta!?

Answer 1

If they are on VHS tapes you have to covert them to cds or dvds there are services that do this, but they are by no means cheap they start at about $7 per tape at the lowest.
Another way do it is get the equipment and hook it between your VHS player for info on this go to

But a different solution would be go to your local library and talk to the people in the computer section if your in or near any large city this would be the easiest, and who knows you might make some new friends
Hope this has helped

Lots to learn, start here:

Google for: transfer VHS to CD tutorial

The key component is a TV Capture card. Google for it, too.

Answer 3

If the videos are VCR tape, then you'll need a converter device that plugs your VCR into your computer. It converts the analog signal to digital. Then you'd want to organize them and store them on discs.

There are several converter products on the market.
