Due to the fixed bandwidth which is purchased for transmission of HDTV broadcasts, some channels use easy stream structures for processing which means that all packets have the same size, whether this is needed or not.
HDTV recordings may contain unneeded data. The optimization process of DVR-Compress allows you to reduce the file data volume without any loss of quality. DVR-Compress filters and removes unneeded information. As result, the recording can be optimized by up to 50% of the file volume without any loss of quality.
