Converting VHS to DVD..how to?

Ive been extensively trying to research how to convert my old VHS tapes to DVD, but have had little luck finding the information I need. I have 2 computers with DVD burners (DVD+R media) but I am just very confused about how I could convert the VHS tapes to DVD’s without a DVD/VHS player, and then record from VHS to DVD, if you can do that. If anyone has any information about how this is done, that would be GREATLY appreciated. Thank you!
