DVD is one of those games that can be played regardless of how experienced a group of improvisers are. All you need is for the ref/improviser at the helm to know what they’re doing, and everything else comes easy. Since it’s basically the same game, I’ll also talk about Television and how to play that one.
DVD is a highly customizable improv game, but usually it’s a high energy scene game. Since there are so many ways to play it, you’re not going to see two different improv troupes play it the same way, and I couldn’t reasonably explain all there is to do within a short amount of time, so here is the basic premise. One person holds the remote (this can be the referee or another improviser), and they have full control over what is happening in the scene. They can mute, volume up/down, pause, rewind, fast forward, change the channel (if you’re playing Television), or skip chapter (in DVD). The biggest difference between skipping chapter or changing channels is that in DVD, the characters will remain consistent, whereas in Television everything changes. (It’s worth noting that Television can easily be played as a group game, with different groups of people acting as different channels. In this case, it’s played very similarly to Four Rooms, which I’ve already talked about.)
The rule of thumb for this game is “do it how it happens in real life”. If the ref calls “Mute!” then the only thing that happens is that you stop making sound. If they change the channel after that, the TV will still be muted, and when they unmute it, you suddenly start talking again, mid-sentence preferably. If they skip the chapter in a DVD, everything changes instantly. Usually this means the start of a new scene (as DVD’s are often broken this way, but not always).
If they change channels, you are now on a different network entirely. I remember the Food Network and the Disney Channel were on button away on our old TV. It isn’t so different now. Depending on how you want to play, however, the ref might ask for suggestions based on what channels they want to be in the game. In that case, the ref should say “Food Network!” instead of “Channel up!” The best takeaway for this is to do what makes sense for your troupe. Come up with your own rules. The only thing that matters is that you all know what’s going on and that you remain consistent.
Another thing to consider is volume changes and rewinding. When the volume goes up and down, an experienced improviser should be careful not to shout. Remember, the scene isn’t changing, it’s only the amount of noise you’re making. If a character is yelling, they should be yelling regardless of how loud they are (and I’d expect a good ref to turn the volume down if you start shouting!) not to mention that when the volume is up really high, blocking should also be loud. Try moving across the stage more loudly than you otherwise would. In the case of rewinding and fast forwarding, this also often mutes the TV. So you just start doing everything very quickly in silence. If you want to go for a retro TV, then speak in gibberish ‘squeaky voice’, because it should still be unintelligible.
I’m leaving a lot out here because the game is so versatile, so just ask yourself how TV’s and DVD’s work. It’s totally acceptable to say “Stop!” during a game of DVD and then go to the bloopers, or pause it to add subtitles (in which case a new improviser should step in and start talking over them in a different language, to your discretion!) The key thing here is that while improv is pretty much open to anything, you need to establish with the rest of your troupe exactly what is in the realm of possibility. It’s not scripting it because there’s still no script, you’re simply discussing what they can expect in these games. Other than that, Television and DVD are basically open to anything.
