Not sure if this is old news, but I'll post it anyway..

Just like Roseanne, the Cosby Show was released with syndicated prints in region 1 and 2.

but... just like Roseanne, the region 4 release (by another production company - Magna Vista Pacific) has unedited episodes :)
runtime 675 minutes compared to R1/2 that has 575, just letting you all know.
