Q: I have a five-year-old rear-projection HDTV that works beautifully when connected to my high-definition satellite TV signal.
I would like to add a high-definition Blu-ray or upscaling (near-HDTV quality) DVD player to my TV system, but the TV doesn't have any HDMI ports. Is there a way to connect the DVD player using component video cables and have it play in high-definition?
A: HDMI (high-definition multimedia interface) cables are preferable for HDTV, but component video cables (typically a set of three) will work on an older HDTV that lacks HDMI cable-connection ports. However, component video cables will produce a somewhat lower-quality picture — experts say component video is not quite as sharp as HDMI. HDMI transfers a digital signal, while component video carries only analog signals.
Q: How can I delete Internet Explorer and use only MSN for e-mail? If I delete IE, will it cause problems with my current MSN e-mail use?

A: Don't try to delete Internet Explorer; you can't do it because it's part of Windows. But you don't have to choose between Internet Explorer and Microsoft's MSN service because they're different things. Internet Explorer is a Web browser. MSN, and its free Hotmail e-mail service, are Web pages that you can view using any Web browser. Just type the MSN address — www.msn.com — into the browser and use the link on the MSN page to reach Hotmail.
