DVD is Digital Versatile Disc. So between that and you claiming success with the Sony we have to define what sort of DVD you want.
Most want a Video DVD and if the Sharp is the usual (old gear tends to not have specs on the web) maybe a DVD transfer kit is next. http://www.fixya.com/support/t13548157-transfer_videoes_from_vl_se10u_sharp noted a system but I couldn't locate it.

I have a older Sharp Slimcam 8mm Camcorder #VL-SE10U that I have 10 cassette movies I need to transfer to DVD, but in the users/operation manual it doesn't say/read how to transfer from the 8mm cassettes to "anything" or shows some kind of transfer cables from there Supplied Accessories or even there Optional Accessories pages. Does anybody out there know how to get my job of transferring from 8mm to DVD's done.
I also have a newer Sony Camcorder that has the same 8mm cassettes but they are Hi8MP Digital 8 video cassettes and it hooked up to this Sony Cassette Recorder/DVD Recorder# RDR-VX525 with a Fire Wire and transferring was successful. HELP!
