I have made 2 ISO files, one AVCHD and the other is a regular DVD.  Both ISOs were from the same Videowave inputs (3 DMSM files).  The AVCHD ISO is half the size of the DVD ISO.  That does not make sense to me, because the AVCHD should have better quality, and thus not compressed as much as a DVD, and thus be a larger size.  Am I missing something????

What are the quality settings you used for each? You  of course have to use identical settings to do a comparison.

Yes, they were both the same -"High Quality"--, but the AVCHD ISO also had the 2 pass encode option selected --very strange.
