Video Mac problems

I took my photograph and changed the data of the .jpeg in a hex editing program, nothing new in my work.

I then tried to capture the image using print screen function, this was then pasted into photoshop and then saved out as a sepreate .jpeg (this was to try preserve the format as opening the "unstable" hex edited .jpeg in differant environments causes a change in how that data is read and thus results are varied)

I then imported these newly saved imaged into video man, and rendered them as a slide show at 1fps using a windows media codec.

When this is views via windows media classic, there is colour information but this strange effect occurs which glitches the images even more. Its as if the codec was unable to read the data and has imposed its own glitch, encoding is a environment I never thought to use!

Colour information has been lost since youtube processing which is anoying cos there was some nice RBG banding across the images.

I am really unsure why this has happened, as I tried to preserve the image as via print screen function. Print screen on Windows must just copy out that data, and when I was pasting it back into photoshop and saving as .jpeg it must just have transported that glitch.
