TV tuner initialization
To further test the tuners' suitability for Media Center Edition, we ran a few tests to examine live TV initialization and channel change time. We used a stopwatch to time how long it takes to initialize Live TV and change channels. The tests were run three times and the results averaged.

Hauppauge takes the crown here with a sub-four-second initialization time. However, the ATI and eVGA cards are only about a second behind.

Our channel change time results are similar. The Hauppauge card has a quick one-second delay between channels, and the TV Wonder and NVTV hover around 1.5 seconds.
