A biodegradable thermoplastic polymer masterbatch composition comprising a blend of at least one biodegradable thermoplastic polymer containing high loading of a particulate filler uniformly dispersed therein. A plurality of workpiece spindles are carried by the housing. One or more contiguous sectors are associated with one or more chunks. The image display unit is designed to perform the operations for motion compensation on operands with various granularity, with the granularity of the operands ranging from one sub-field individually to a group of sub-fields together. To increase quality and to allow less qualified personnel to operate the machines, a parameter set based on rough entered data is compared with templates and that a most similar template be used to set the production step or steps. In a medium that recordsplays back data including video data and control information, the control information includes information for accessing a specific portion of the video data.
