screen recorder problem

[theevilsam]

Hi. i have a windows 7 64 adn i just downloaded a load of free screen video recording softwares. they all installed properly (not at the same time, i used the next when the one befor didn't work) and they all record fine, kinda. its just that they wont record the whole screen. they only record the top left hand side of the screen... i have set the area of recording to cover the whole screen but this dosent work.


any ideas anyone. i'm trying to record my powerpoint presentations to put on dvd

thanks for any help
