Replying to HELP - exporting in Adobe Premiere Pro 2.0

i had no problem exporting when i used premiere pro 1.5, but i just got 2.0 and im having some problems with exporting. I do the same thing, which is; quicktime --> mpeg4 , spacial quality around 80sh, and FPS at 30 cause its just a short 1min edit. But that doesnt seem to work at all with 2.0. With 2.0 i do that and it exports it so the final file size is like 1 mb, when it should be probly 20ish, and the quality is horrriiibblle. I've even tried setting the spacial quality to 100 and its gotten no better. Help me out please.
