Not that I feel any real need to defend Philips, but where is the "glaring shortcoming" with this TV set? I'm getting confused as to why anyone would care about what's switched on or off unless it measurably affects what you're seeing.
Scanning backilght affects image quality by eliminating motion blur - a common shortcoming with LCD sets.
On HD, it's turned off, meaning that motion blur is back.
That's all. Hardly a huge deal, but it does make some people wonder.
Other shortcomings of the set is that sometimes, depending on the settings, very obvious MPEG macro blocking is displayed.
I'm not attacking Philips, i love them, i'm just reporting what i see on the AVForums.
