    Of course. A computer's video card automatically scales everything to the chosen resolution.

    I don't have much experience connecting macs to televisions but I assume if mirroring you just set the macbook's resolution closest to your tv's native res to limit the amount of scaling your tv has to do.

    afaik you will drop quality in the conversion from DVI to VGA.

    You mean like a digital to analog conversion? But doesn't the macbook already support VGA output, so nothing to convert? And the mini-DVI to VGA cable is just carrying an analog signal over. That was my understanding anyway. There's still the analog vs digital debate but with a good cable the difference should be negligible on a tv.

    Wikipedia says that the mini-DVI-to-DVI cable does not carry a VGA signal.

    That's all you really need to worry about.

    Yeah, that's 'cause it's DVI-D, digital only. Apple could supply a DVI-I cable and make everyone's life easier but I guess they'd make less money that way.

    No, but there's a mini-DVI to VGA cable as well. I'm not entirely sure what you mean by upscale though. Do you mean if you have a MacBook plugged into a TV with a higher resolution than the MacBook, will it output to that resolution? If so then yes, provided you're not mirroring the screens. If you mirror the screens, you'll end up with a centred image the size of the MacBook's resolution on the TV screen. Dual-screen mode and single screen with the MacBook closed work fine.
