The DMP-B100 operational speed is comparable to the slower stand-alone Blu-ray players we've tested this year. However, we will note that the CNET speed rating is calculated taking advantage of the DMP-B100's quick start mode, which doesn't work when it's operating off the battery. If you take away the DMP-B100's quick start advantage, it has a CNET speed rating of 67, which would make it the slowest player we've tested this year. The bottom line is that though the DMP-B100 is on the slow side of players we've tested in 2010, it's not that far off, and we think it has acceptable performance for a portable model.
