Incompatible Format error

I have two computers. 1 is a G5 dual 2GHz the other is a 17" macbook pro. They both are running the same version of DVDSP 4.2.0. I have 8 different DVD's that were all encoded exactly at the same time in the same way (compressor) each are m2v and ac3. I have no problems on my G5, but I thought I'd try to save time and burn some from the macbook pro and each time I try to import I get the incompatible format error for the m2v....

Any suggestions?
