it says it has a removable hard disk & compact flash card ?
What they mean by this is it has "internal memory", so if you have no CF card you can still take pictures and save information to your camera. But it is probably fairly small.
The reason they say it works like a removable hard disk is because if you connect it to your PC it will show up as an additional drive, so you could copy your Word documents or small files onto it and transfer to another PC.

2. Is this the "CD" with the program? {not to go into the camera }
The CD that comes with cameras normally contains drivers and software so that you can view pictures/movies that you download from the camera onto the PC.

3.what is the difference in the Quality of the flash cards
Ive investigated a Little and see 1000 times and 1 to 5 million rewind/clear times
Afraid I can't find much information on this. The only thing I can think of is it is saying that you can change the resolution on the camera.
So instead of recording at high quality (which uses a lot of space) you can lower the quality and therefore fit more onto your cards.

its also got MPEG-4 technology what all these terms mean I'm not exactly sure any help is greatly appreciated
MPEG-4 quality is just saying that it records at high quality. (supposed to be as good as DVD quality)
Some cameras record at a lower quality so they are just emphasizing that this is "high quality"
