But I've tried a whole bunch of screen recording software (all free shareware from the net) and none seem to work -- an error always occurs whenever I maximize my Diablo2 window.
For example, in the case of Hero Screen recorder, the error is "courseware2.exe has encountered a problem....needs to close"
I tried another game, Warcraft 3, and it was the same error.
I cannot speak from personal experience, but I have seen the SnagIt program highly recommended in several computer magazine articles. While not free, they do offer a free 30 day trial, so you will be able to tell if it works for you:
yes,SnagIt is great. i have been using it for a long time.
recentlly i have used kind of screen capture software calledACA Capture Pro, i think it can handle it .
both fraps and snagit will do a good job, however I'm have not used them for a while so I'm not sure which is best but fraps advertises as being able to record games
