Help burning SVCD DVD rip with Nero!!

I'm new to burning vcd's and have burned a few but, I'm trying to burn an SVCD DVD rip of a movie with Nero and I'm not having much luck. When I drop the MPEG file in, I get a prompt saying it is an invalid resolution. Does this mean I need a codec or something? Or do I have to adjust something in the settings to burn SVCD?? Anyway I choose ignore and continue with the burn.. it burns but won't play properly in my DVD player. I can see a picture but there are green lines and blotches everywhere and it freezes up. In fast forward I see the picture better and it looks very good. How can I burn a proper copy of this mpg!? I'm getting Nero 6 Ultimate.. not sure if this will help with my problem. In the prompt it asks if I want to re-encode the file, will I lose quality if I do that? I know it takes forever too. So is there any way I can burn it without re-encoding it? Is my DVD player not compatible? Or is this file meant for DVDR? I'm just a rookie at this but this svcd stuff is a major headache and seems like it's not even worth the time and hassle. Any info or help would be much appreciated.

Thanx
