to copy an analog input like records all you need is a line from the record player to the input on the sound card. usually you would use mini-audio connector which is a regular connector same as on most headphones for a walkman.
you would use any program that can record input like soundforge and save the sound as a wave or mp3. you would than burn the music with nero or any other burning software.
to get VHS to DVD you need a dvd burner and a video card that accepts video input from your vcr. in this case you need RCA inputs. you can also get a tv capture card but this has the best picture quality for recording:
capture the picture to MPEG2 with that video card and use nero or any burning software to create a dvd-video disc
