I have a MacBook Pro 2.2 and when I try to connect the DVI cable to the HDMA in my Panasonic TV the screen goes gray and the computer stops responding and I have to restart the computer. What can I do to fix?

I don't see why they would switch from DVI to HDMI. The signals are literally identical (thus why you can adapt between the two with a simple wire) and DVI's connector design is better suited for computer use. HDMI is a home theater interface. That's why the only PCs you see it on are "media center" machines.

If you want to hook your MBP to a TV that lacks a DVI port, go buy a $5 adapter and be happy. Again, it's electrically identical, so the adapter is just changing the shape of the plug and thus costs practically nothing.

I connect my PowerBook G4 (17) to HDMI monitors and TVs all the time. It properly detects screen resolution and aspect ratios, plus you can change the resolution depending on specific needs. The only thing that it does not have is audio since DVI does not have it. you then connect the audio with an analog mini-to-RCA cable. Most TVs will let you input the audio through an analog connection. You can also mirror the display.

There are adapters and cables. I personally use and prefer the cable (DVI-HDMI). If you buy carefully, you can get a decent cable for $15.

For now, I think you'd be better off with DVI since it has digital and analog outputs in the same connector. HDMI is only digital so your hardware would require an additional port for analog connections, taking more space and adding cost. HDMI is great since it can carry 8 channels of digital audio. For most laptop uses and scenarios, HDMI is not a necessity. For desktops it may be different (the Apple TV has it) and if you have a tower workstation, you can add it as an expansion card.
