How do I skip videos in the Portal 2 co-op?

Solution 1:

You are at a loading screen if you can't see each others messages and in-game when you can.

During the video in the beginning of co-op play you can talk, which means that you are in-game. You can use this time to chat with your friend in advance, but if you play regularly with someone you know this can indeed be annoying. While trying around yesterday I have noticed that you can influence the settings of the co-op game.

Thus the video in the beginning can be skipped by changing the host time scale:

1. sv_cheats 1

2. host_timescale 16 (if it works, it should up the video by about 16x, shouldn't take long)

3. host_timescale 1 (Set it back, or you'll be unable to play the game properly)

These server-side settings are adopted to the other player, so you'll see them executed twice.

The videos between the hub/chambers can't be skipped, because they are loading screens.

Notice: You can not get achievements for that game anymore...
