IF you use the same material for both, and render at the highest quality for each format, then yes, there will be a big difference. The DVD will be much better quality. And a DVD is more universal than SVCD. Not all DVD players can play SVCD discs.
Thats exactly what I wanted to hear..... i was hoping the quality would be better. i was never impressed with SVCD's. However my limitation may be with my camcorder.
