Pan-scan's strange relationship?

[kimiraikkonen]

Hi,
I have a 704x576 video and when i run it in "full screen" mode, it's displayed as a frame but there are black-backgrounded edges on left/right and top and my desktop resolution is 1024x768.

So, i was always doing "pan-in" to fit the screen but although "remember pan-scan settings" is selected, when i re-open the video, everytime i have to do re-"pan-in" to fit.

Yesterday, i found out a checkbok named "cut top and bottom of video in full screen mode" and i thicked it. After that the video is ran with strected and fit on the screen as i wanted. So i do not need to do pan-in anymore.

So, what is the relationship of pan-in, "remember pan scan settings" and "cut top and bottom of video in full screen mode" ?

Thanks....
