1. Technically I think you are allowed to make ONE copy for your own use (provided you retain the original VHS)
2. Any that writes DVD,s BUT check that your DVD player will play them click here to check your DVD player
3. You need a method of connecting VHS player to PC (usually phono plugs to Graphics card or external USB device), software to copy to, burning software that will burn to DVD format (VIDEO_TS files)
And thats basically it!
No its not that simple - I spend hours working at it .... but the results are worth it cause all my tapes are home videos ;-))
Post back if you want more info
