make a new sequence and set it to your original shooting settings. Then drag the old (wrong) sequence into the new one. When premiere asks if you want to change settings click no. Sounds like your sequence settings got a little confused, Or if you dragged a sequence into another with incorrect settings. Nice feature for doing DVD and Bluray from a single master timeline.
