Thanks for the reply! I've tried recording the button sequence on PC, but unfortunately, most (or all) PC games have some random factor (suppose it's caused by a hardware lags, when the physical engine is forced to use a larger time step and could "miss" some event it had processed correctly before). This effect breaks a demo playback in most cases, so it seems the only way is to record every entity's position, velocity, and other game parameters to restore them during playback forcefully, sometimes allowing the interpenetration of physical objects or processing a hit even when a bullet have missed the target, if that is written in the recorded file. That would be as difficult for the anti-cheating verification as a video file. Anyway, could you give me some links to these "multimedia TAS" videos? I'd be happy to see them!

Greetings. I'd like to share some technique of TASing a PC games. You can see the samples here: http://www.youtube.com/watch?v=Z75TJnFkcqs and here: http://www.youtube.com/watch?v=ldiwOxwe2r8 Sorry for a bit too enthusiastic descriptions, at that moment I haven't seen any of TAS videos and was quite impressed by the idea. So, here's a deal - I've written a library, similar to Speed Gear, but operated by a Shift key, which is able to slow down almost any game, and I'm looking for someone willing to help me integrate it with a screen capture software. As you can see, I've recorded the videos above at full slowdown and edited them manually. It would be too difficult to find every place where I used slowdown key and restore the original speed. If there were some software that could change the capture framerate when a specific key is being held down, people could use it to make TAS on PC. Also, this software could exploit the quicksave/quickload keys to make segmented videos, able to rewind and continue after a quick load. But it's not essential, cause even a quick save/load is a slow operation for modern games and there is no way we could juggle them just as easy as NES games on the emulator.
