Sony Blu-ray players do not provide scrubbing or position feedback, unlike Panasonic’s 2012 and 2011 models. On the other hand, the Sony 5100 does provide Media Identification (what is the name of the disc/title) for both discs and streaming (for instance, if you watch Netflix, what is the title of the program, etc.) which none of the Panasonic models do.
It’s a tradeoff. From a pure control perspective, the Panasonic 2012 models are now a good bet since they finally fixed the power issue a few weeks ago – we would assume they fixed that because they know the 2013 models are useless. Perhaps it a sign they took development back in house for 2014?
Of course, then there is the fact that CES 2014 starts next Monday and who knows what claims will be made about the new models. Let’s not forget however that Panasonic reps stated unequivocally at CES 2013 that their BD players would have the same IP control as the 2012 models and we know how that turned out so it is often several months before what happens next week can be tested and verified.
