Kim Komando solves your technology problems


Q. I’ve been reading a lot of news stories about cell phones and cancer lately. But what about Wi-Fi? Does it carry similar risks?

A. This question is somewhat misleading. Studies on cell phones and cancer have been inconclusive. But Wi-Fi and cellular signals are essentially the same. Both are electromagnetic energy. There are only two real differences: the frequency they use and the power behind them. Cell phones have more powerful signals because they connect to towers miles away. In comparison, Wi-Fi only has to extend a few hundred feet. Also, you hold your phone up to your head. That means you’re closer to the source. So, cell phones pose a far greater potential threat than Wi-Fi.

Q. I just updated to iTunes 10 on my Mac. I like the new features, but I don’t like the new title bar. The buttons aren’t where they were before. Can I change back to the iTunes 9 title bar?

A. A lot of people don’t like the new title bar in iTunes 10. Fortunately, you can get the iTunes 9 title bar back. Start by upgrading to iTunes 10.0.1. Then, install a free program called TinkerTool. It will give you access to a lot of hidden options in OS X. Once you install TinkerTool, open it and go to the iTunes 10 tab. Select "Use standard window with title bar and horizontal buttons." Close TinkerTool and start iTunes. The title bar should have the same layout as in iTunes 9. Visit Komando.com/news for a link to TinkerTool.

Q. I’ve made some videos for a product I manufacture. How can I get these videos onto a DVD? I want to play the videos on a TV.

A. The first thing you need is a DVD burner. Most computers nowadays will have one installed already. Second, you need DVD-authoring software. This software will create DVDs that work in standalone players. If you use Windows 7, try Microsoft’s Live Movie Maker. The version of Movie Maker included with Vista Home Premium and Ultimate also authors DVDs. If you have a different version of Windows, you need a third-party program. I recommend using DVD Flick. Download these programs for free from Komando.com/news.
