The movie industry has embraced 1080p24 as a digital mastering format in both native 24p form and in 24PsF form. 1080p24 has become an established production standard for digital cinematography and there is plenty of equipment capable of capturing and processing 1080p24 signals. This may be the first universal video standard which transcends continental boundaries, an area previously reserved for 24-frame film.[2]

For live broadcast applications, a high-definition progressive scan format operating at 1080p at 50 or 60 frames per second is currently being evaluated as a future standard for moving picture acquisition.[3][4] EBU has been endorsing 1080p50 as a future-proof production format because it improves resolution and requires no deinterlacing, allows broadcasting of standard 1080i25 and 720p50 signal alongside 1080p50 even in the current infrastructure, and is compatible with DCI distribution formats.[5] Recent studies show that for digital broadcasts compressed with H.264/AVC, transmission bandwidth savings of interlaced video over fully progressive video are minimal even when using twice the frame rate, i.e. 1080p50 signal (50 progressive frames per second) actually produces the same bit rate as 1080i50 signal (25 interlaced frames or 50 sub-fields per second). [5][6]

In Europe, 1080p25 signals have been supported by the DVB suite of broadcasting standards. The 1080p50 standard has been foreseen as a future-proof production format, and eventually a future broadcasting format.[3] 1080p50 broadcasting should require the same bandwidth as 1080i50 signal and only 15-20% more than that of 720p50 signal due to increased compression efficiency,[5] though 1080p50 production requires more bandwidth and/or more efficient codecs such as JPEG 2000, high-bitrate MPEG-2, or H.264/AVC and HEVC.[8]

It's all in the language;

"...HD video with stunning detail at full 1080p resolution and 25 FPS..."

It is 1080 resolution, which doesn't matter whether it's i or p, it's still 1920 x 1080. I don't think it's misleading advertising, it's just very badly worded - as is the whole meaning of the various "standards", and phrases, around HD TV.
full hd means it does 1080i full hd 1080p means it does 1080p and there is a big difference, and it does matter if its i or p,

1080i: 1,920x1,080 pixel resolution. High-definition picture that is displayed interlaced. Each odd line of the picture is displayed, followed by each even line, and the resulting image is not as smooth as a progressive feed. 1080i is therefore a more detailed picture suited to documentaries and wildlife footage, but less suitable for action-oriented material such as sports and movies.

1080p: 1,920x1,080 pixel resolution. High-definition picture that is displayed progressively. Each line is displayed on the screen simultaneously, therefore it is smoother than an interlaced picture. This is the ultimate high-definition standard -- the most detailed picture, displayed progressively.

There are two main formats for HDTV, namely 720p (i.e. a 720 line picture progressively scanned 50 times a second) and 1080i (1080 lines interlaced at 50 cycles per second). The picture resolution of a high definition digital TV is about 4 times greater than a typical 576 line TV picture.

it will be noticible on bigger screens over 32" 1080i is no good for fast moving action.

i use Win 7 (Ultimate) and love it so much easier than xp.

just go for a k5, otherwise you will buy a k7 then sell it.

Anne sorry if you feel there are emotive connotations with a word that also means "counting badly" or "difficulty with numbers". You could use it without the capital D. It was meant descriptively, not pejoratively.
All good doug, just gotta chill more i have

dyscalculia
From Wikipedia;
Dyscalculia or math disability is a specific learning disability or difficulty involving innate difficulty in learning or comprehending mathematics. It is akin to dyslexia and can include confusion about math symbols. Dyscalculia can also occur as the result of some types of brain injury.

Has April fool come early?

Yes i know what it is, I just think there is no need for it. As there could well be people with Dyscalculia on here and no one is perfect.
