Hack 12 Controlling Overshoot Protection

Rather than turning off overshoot protection, fine-tune it to suit your fancy.

So you turn off overshoot protection [Hack #11] and find there's some value to having TiVo do some of the driving for you. You'll be happy to know there's a middle ground. Instead of turning off overshoot protection entirely, you can adjust its granularity.

Using the Node Navigator [Hack #16], carefully navigate to node number 1 and select it to access overshoot settings.

The Set Over Shoot Value menu, shown in Figure 1-4, shows exactly how much control your TiVo is going to give you.

Figure 1-4. The Set Over Shoot Value menu

When you are fast forwarding or rewinding, and you hit again, your TiVo reverses the direction for a specific number of seconds and starts playing there�that's your overshoot. The faster you are moving through the program, the larger your overshoot is set, by default.

In the Set Over Shoot Value menu, there are five different speeds that your TiVo has overshoot set to. If you hit once, you zip backwards at "Speed -300". The second and third times you hit , you go back at "Speed -1800" and "Speed -6000", respectively. Likewise, if you hit twice, you zoom ahead at "Speed 1800", and the third speed is "Speed 6000". If you play with your TiVo's remote, you'll see that there is no overshoot protection for fast forwarding just once.

To set the overshoot value for each speed, scroll down to the speed you want to change, use your remote to type in the value, and hit Enter to commit the value. Setting any one of these speeds to 0 will turn off overshoot protection, and every 1000 in the value set is one second of overshoot. For example, with "Speed 6000" set to 48000, if you are going through the program after hitting three times, hitting will rewind the stream 48 seconds before playing again.

If you change your values and forget the originals, don't just hope a reboot will fix it; these changes are fairly permanent. Just refer to Table 1-3 for the default values.
