All the other features of the 32PFL9613D are the same as the 32PFL9603D, from the Full HD resolution and high claimed contrast ratio of 55,000:1 through to its use of Philips' powerful Perfect Pixel HD video processing. So rather than go through all of the 32PFL9613D's features again in-depth here, I'll just refer you to the 32PFL9603D review, if that's OK!
And so we get to the main point of this review: finding out if the addition of 100Hz really makes a difference, and finding out if the 32PFL9613D's aging heritage prevents it holding up against the latest LCD hot properties.
Regarding the first question, the answer is a surprisingly emphatic yes. Though maybe not in quite the way I anticipated.
For while motion is slightly less affected by blur and resolution loss than it was on the 32PFL9603D, the really cool thing is that the 32PFL9613D's pictures seem less afflicted by the sort of unwanted processing side effects that I had to work so hard to counteract with its predecessor. And so objects passing across the screen seem less dramatically joined by such processing-related problems as shimmering halos and flickering, even with the controversial Perfect Natural Motion circuitry switched on.
This initially seems a bit of a strange finding given that the addition of 100Hz is actually piling more strain on the TV's video processing engine. But what I suspect is happening is that the 100Hz is easing the load of the Perfect Natural Motion processing component. And as the old saying goes, a problem shared is a problem halved.
This makes the 32PFL9613D notably less demanding on you, the end user, because avoiding the motion processing issues with the 32PFL9603D required regular visits to that TV's onscreen menus to reduce, or deactivate entirely, various noise reduction and Natural Motion circuitry. On the 32PFL9613D, I found myself much less regularly tempted to tinker with the settings I established while first calibrating the TV.
The addition of 100Hz also gives you more options if you do want to tinker, mind you. For occasionally I found that if the set's motion processing was glitching a little while watching data-heavy, action-packed HD sources, turning the 100Hz element off but leaving HD Natural Motion on sometimes solved the problem - a degree of subtlety not possible on the 32PFL9603D.
With that in mind it's perhaps a pity that Philips hasn't stretched the flexibility of the new 100Hz system to one further option: the ability to leave 100Hz on while turning HD Natural Motion off. But that's me: always wanting the world and everything in it!
