I've been doing alot of them lately.
What kind of dvd player do you have? First thing you need to do is go to the site stated above
www.vcdhelp.com and look your exact dvd player up in the search and see if your player has any issues with playing vcd or svcd.
I have a kickass toshiba thats a couple years old that doesent play any cdr media, i just recently bought a cheap Curtis thats said it did on the box but after burning several to no avail I looked it up on the site and others had the same problem.
One of the cheapest players that will play just about anything you stick in it is the Mintek available for 50 bucks at BestBuy. Plays all mpegs, mp3's burned on dvdr or cdr or even cdrw. Its in the list on the site with good reviews as well. My parents have one and I tested it, works great.
Chances are you can just burn the mpegs you already have to disc and this player will play it.
Cheers,
