LOL - do you think its going to be easy?
Start here!

mpeg is 1/4 screen - NOT DVD quality.
mpeg2 can do 720 X 486 or whatever, that's full screen. The DVD format you
master to disc is a whole-nother story. Start reading and find some good
master/burning software, cheap. What DVD Burner do you have?
You didn't need an All-In-Wonder, actually a good quality Pinnacle card
(
http://www.pinnaclesys.com/) would have been a better choice. Recording
quality is 10X better even on one of their cheaper cards. The All-In-Wonder
is more like a novelty or toy in my opinion. Good for small mpeg caps of fun
stuff. I've had one some time ago, and I have a couple of Pinnacle's (DC10+
and a StudioAV). I've had Hauppauge and a couple of Targa cards too.
S-Video (SVHS) is for Super-VHS, there special type units and are still very
expensive (considering). Standard 2 or 4 head VHS use RCA which is ok for
consumer grade stuff. Either way you need to convert an analog audio and
video signal into a digital one and retain the sync, that's the hard part.
Finally getting formatted in one of a dozen or so ways and then having a
piece of software master it to a burner and onto a blank disc.
Have fun.
