Best video format for AGS

[Problem]

I didn't know this plugin. Looks interesting, though I guess it will only be useful for the Windows build.

[Problem]

So, in case anyone else is interested: The solution for Theora videos in AGS seems to be playing a silent video and having the audio as a separate .ogg file. This way the video stutters a lot less. And even if it still stutters a little, the audio remains intact and the timing is still correct. The video keeps up even if it has to skip frames.
So even if the video is slightly choppy on some systems, we can get rid of the annoying audio dropouts.

I'll do a couple more tests, but so far this seems to be the best solution that doesn't depend on any installed codecs.
