Sony Pictures Home Entertainment has announced its first multi-disc UMD titles. The videos are: Good Times - The Complete 1st Season (2 UMDs) and Sanford & Son - The 1st Season (3 UMDs). These multi-UMD videos will both be released on November 1 and will retail for $29.95.
Looks like multi umd software is actually going to happen.
