I have the first four OpenSuSE 10.1 CDs (did I mention that I'm now on an unlimited download plan?); I found that I needed CD #5 for installing the KDE development packages, so off I went to the download page. There I found that the ISO images were now adorned with the moniker 'Remastered', whatever that means. I didn't pay much attention to this and went ahead with the download. Big mistake. When trying to install the packages from this CD, YAST refused to proceed and kept whining that I was shoving in the wrong CD.
Googling reveals that the FTP mirrors contain the original ISOs as well as the 'Remastered' ones. Grrr.
