There have been a number of reports about ScummVM misbehaving on some hardware under Windows, but that these can be worked around by telling the SDL library to use different video and audio drivers. This information ought to be in the ScummVM FAQ but isn't.
I propose that something like this is added:
ScummVM starts, but all I get is a transparent window!
This problem has been reported to happen under Windows in some cases.
Check that you have the latest drivers for your graphics card. If that
does not help, try setting the SDL_VIDEODRIVER environment variable to
"windib" and try again.
ScummVM runs, but sound is stuttering and/or garbled!
This problem has been reported to happen under Windows in some cases.
Check that you have the latest drivers for your sound card. If that
does not help, try setting the SDL_AUDIODRIVER environment variable to
"waveout" and try again.
How do I set an environment variable?
That depends on what operating system and/or command shell you are
using. Under Windows, you could try creating a file called scummvm.bat
in the same folder as scummvm.exe. Open this file in your favorite
text editor and put something like this in it:
@echo off
set SDL_VIDEODRIVER=windib
set SDL_AUDIODRIVER=waveout
scummvm.exe %1 %2 %3 %4 %5 %6 %7 %8 %9
You should now be able to run ScummVM by double-clicking on this batch
file, instead of the ScummVM executable.
On more recent versions of Windows, you can also set an environment
variable permanently through the control panel.
However, I do not currently have access to any computer running Microsoft Windows, so it's a bit like flying blind here. So this text would have to be fleshed out and proof-read by someone who actually knows Windows. In particular, I'm a bit uncertain about the .bat file syntax...

Not using windows, but I think SDL_VIDEODRIVER should be SDL_AUDIODRIVER here.
does not help, try setting the SDL_VIDEODRIVER environment variable to
under "ScummVM runs, but sound is stuttering and/or garbled! " - should be changed to SDL_AUDIODRIVER as well I think
a note on naming the batchfile SCUMMVM.BAT: this won't be a problem as long as you start it by clicking on it - but if you use the commandline and just type "scummvm", the .exe will execute (the order for identically named files ist: .com .exe .bat)
I read it but somehow thought it referred to the code in the batchfile and was subsequently changed and this was a 2nd error - meh, I should learn to read
apart from the typo (configration?), this line is not printed that way anymore by current builds - maybe we should remove that question, or add as a workaround "please upgrade", or at least note that it's obsolete?
(it now displays: Creating configuration file: C:\WINDOWS\scummvm.ini)

Also, (semi-shameless self plug, hey it took me a while to make ) perhaps people would like to be pointed to useful ogg/mp3 compression resources like my Ogg Compression Guide. Few handheld devices have the free space to hold uncompressed games in their storage.
So is this in good enough shape that it could/should be added to the FAQ? As I've probably already said, I don't have access to any computer running Microsoft Windows at the moment, and I'd really prefer it if someone who did could take care of it.
