If you have built your computer correctly then the "Print Screen" button should work flawlessly - I've used it under Windows and Lenux; so I know it works when the computers they have built done correctly ^^

No, it shouldn't, unless you've got a video card that's 10 years old and doesn't use hardware video acceleration for all video playback.

Unless you're using (1) special drivers, (2) a different capture program OTHER than the default Windows facility, or (3) no hardware acceleration, PrintScreen won't do anything.

None of those cases are the most common case, so you don't have much of an argument when saying "but it works in a properly configured system!" unless you want to prove that MOST computers are misconfigured (and then you'd just have a mess on your hands).

Windows captures via the GDI. (On a GNU/Linux machine, you can configure the same behavior.) The problem is that 99% of modern video cards do NOT use the GDI for video playback as it's just too slow; they take a different, more direct path.



And I know for a fact that "regular" screen captures don't work to capture content being played using XFree86's Xv extension, on a FreeBSD, GNU/Linux, or any other UNIX installation. (They sometimes work when you use OpenGL acceleration, but most people don't, since Xv is usually superior).

Might work with some other X-server, but not the most common one.

? what's wrong with OpenGL ?

if it were not

for it, then

this wouldn't

have been subbed T_T

Did you read my post?

More importantly, what do all those screenshots and subbing have to do with anything?

I said that OpenGL output can sometimes be captured using "regular" screenshot methods on XFree86 -- a very specific case that I threw in for the heck of it. However most hardware-accelerated video playback is done via hardware overlaying and cannot be captured using said "regular" methods. Programs like SmartCapture can capture that data, but not Windows' built-in screenshot facility, which is what you said would work.

erps!

sorry; it's always worked for me and its one of the first things I check for when
Ibuy a new Capture Card

I either use virtualdub or ctrl+i in windows media player to get DVD screenies.
