No it is an actual real feature, basically indicating 100Hz+ refresh rate & fps generation by the DSP, but again perceivable difference will depend on content.

But why wouldn't the set run at 100Hz+ by default? Why would the manufacturers by default have the set running below that refresh rate?

Not sure what your asking, but the D550 does not have this functionality, it is only a 50Hz set (can do 60 as well). Therefore its signal processor is only capable of processing/generating 50 fps.
A 100Hz TV will produce/display 100 fps using interpolation, mathemetically deriving an additional 50 intermediate frames which are inserted inbetween the original 50. This should provide for smoother motion (inc probably reducing/eliminating the ghosting discussed) but there is also a downside, picture looks more fake often refered to as the SOE (Soap Opera Effect).

My TV's Motion Flow is enabled by default.

Oh okay. Pardon me, the option I have is motion lighting, not motion flow...
Hence the option to switch motion flow off, again makes sense..

+1, and sums up why 720p is preferred over 1080i most of the time.

ok so i got my bonus and decided to go 50" plasma FHD 3D.
two options: Samsung PS51D550 and LG 50PZ550.
saw them both at the shop and couldn't make out much difference. any experience with either?

Which is least reflective?
Which is most aesthetically pleasing?
Boils down to that IMO.
Just make sure you test thoroughly.

Dont see the linkage, 100Hz+ (or MCFI - motion compensated frame interpolation) and de-interlacing are seperate processes with different aims. A 100Hz TV displaying a 1080i feed would be doing both, first de-interlacing then MCFI.

Because "i" means fake data is added (or copied). Similar to how 100Hz adds data. That's how I imagine it.

You dont have to wait till then, the differences between the various HD sports feeds are quite apparent most of the time.
Was watching the Copa football the other night and it had quite noticable ghosting, flipped to another HD channel showing netball (obviously for testing purposes only
) and it was perfect, no ghosting or other types of motion corruption.

Samsung looked less reflective but the LG was slightly higher up. WIll check again when i go back. btw was very impressed with the 2D to 3D conversion.
Also have to say that the brightness on the Plasmas were no where near those on the LED tvs I saw when both were set on full. Tempted to go for an LED But then again the price on the 40" LED was the same as the 50" Plasma.
Edit: also the colours on the LED were much more vibrant. The colours on the Plasma looked softer/more natural. I guess which you prefer is personal preference in that regard. I preferred the LED but i don't think i can look at such an image for too long without my eyes complaining.

In your home, it's very unlikely you'll need to run plasma anywhere near full brightness.
If you have the budget for the PS51D550 and are not bothered by the reflections I would go for it. Huge screen and FHD, you get much more than with the 40" LED.

More fixed up than fake. A 1080i picture is made up of 1080 individual discrete lines of pixels, but to save on bw reception of the odd & even lines is staggered by 1/50th of a sec.Because "i" means fake data is added (or copied). Similar to how 100Hz adds data. That's how I imagine it.
Think of it this way, if a stationary camera is recording a static scene, there is no difference between a 1080i & 1080p picture. When motion occurs the DSP has to intervene to fix/clean up the corruptions introduced by the fact the either the odd or even lines are stale by 1/50th of sec.
The actual algorithms used by the various vendors are a trade secret, so its difficult to tell how they achieve this. But from my experience they do a pretty good job, again dependant on the quality/accuracy of the source feed.

Just setup my 51D550. Looks great so far. Do these tv's need to be "broken in"?

According to Samsung, not any more.
I still would though. Run at half brightness/contrast for a few days. Leave it on a TV channel over night for 2 or 3 nights etc.

There's a warning in the manual about static images causing image retention and/or burn in. Do I have to worry about things like the CNN logo etc?

Nope.

Well, you will in some cases still get image retention, but it is not permanent... If you watch a movie with black bars (for example a movie with 2.35:1 aspect ratio) you will probably see faint lines where the bars were for a few minutes on a full screen image afterwards. Occasionally it is worse, and people have image retention for a few hours, but it is relatively uncommon.
In general, with modern plasmas you don't really need to worry about it.
